You posted that your brother doesn't even know that the weekend in question is when your're graduating. Once he knows they might change it. Expecting them to put it off a month though is IMO, asking a bit much.
You're assuming a whole lot of things. If this is college, who knows if you'll graduate right at that time. Dates change for both high school and college graduations.
Before flying off the handle, talk to your brother. Apparently you and your mother cannot discuss this to your satisfaction and after all she doesn't have any say in the wedding date chosen.
I will tell you if my brother scheduled his wedding on the same weekend as my graduation, i wouldn't have to tell him to move it. My mom would. That would be the first thing of her mouth. YOu aren't being selfish and if you were my daughter I would tell him to pick another day. If he didn't we would probably have a big problem on our hands.
I don't see college graduation as a huge thing compared to weddings, but I would be upset if my family acted like me missing my graduation wasn't a big deal when big deals were made out of the others.
Call your brother! There's no reason to be upset if he doesn't even have any idea of the date of your graduation.
It's a long time away. If he can't be bothered to come up with a different date at this stage of the game when you have a milestone event already on the calendar, you do have a big problem.
I don't see the big deal of the next week. Graduations are a one day thing. My parents are in their 80's and although they are in good health they would be choosing which event to go to even if they were a month apart if they both involved substantial travel.
Your grandparents are aging, you may need to let go of some of your expectations earlier than you had hoped. I'm the youngest child too, and my events simply weren't attended the same way as my older siblings were because my grandparents were older when my events happened.

Did your Mom call you selfish because you didn't want the wedding on your graduation day OR because you also were angry about the weekend after?Okay first question...can anyone else NOT edit posts???? It wont let me edit anything.
Second, it is college graduation and graduating in 2013.
We get 5 passes to commencement for each graduate. So my grandparents and my parents only make 4.
I dont know. re-reading my post I can see that I was overreacting when I wrote this. I was just very very frustrated.
I still think that it isnt fair but when I told my mom that I wouldnt be missing my graduation for his wedding and that I wasn't too thrilled about it being the weekend after either, she told me I was being very selfish so that just hit me hard and it hurt.
I would NEVER actually insist on it being a month after graduation. I would prefer it but obviously never INSIST on it.
I mean, whatever happens, happens and i'll deal with it and enjoy both graduation and my brothers wedding. With graduation, moving, flying cross country, the wedding, etc, it will just be A LOT in a week.
I dont know...I just needed to vent and was really wondering if my though process was really me being selfish about it.
This. Especially the bolded part. My parents are in their 80's and there is NO WAY they would travel more than an hour for anything, and then we'd have to drive them. That kind of stuff just gets too difficult for older people to manage. We had a family wedding in December 2009 that was 30 minutes away. Because it was a winter wedding and an evening reception, we decided to stay overnight @ the hotel in case of bad weather...no sense driving home at midnight in the snow. We took my parents with us, and you would have thought that we were asking them to climb Mt.Everest carrying a sherpa-pack. I made their hotel arrangements, helped them pack, we drove them, I got them settled in the room, we drove them to the reception and it was STILL a MAJOR stressor for them. We have another family wedding in Long Island (1 hour away) in May and they have already proclaimed that they are not going.
If you have a good relationship with brother and his fiancee, why not talk to them and say "I hear you're looking at Spring 2013 for your wedding. I just want to let you know that my graduation date is June 1, 2013, so you can avoid that date".
As far as what your parents "did" for their other kids....parents are able to do different things at different times based on lifeand family circumstances at the time.

How is the brother selfish? He doesn't even know there is a conflict.I think it's extremely selfish of your brother and his fiance. He had HIS time to shine at his graduation, he should be respectful of the fact that it is YOUR time to shine at your graduation. June ain't no big for weddings anymore. October is the big time now.
