A couple of people mentioned weddings close to high school graduations of a sibling. This time a year ago I wouldn't have really gotten that at all. Having just gone through it this year, though, I can see why it would be tough. Senior year is exhausting, expensive and emotional, and that's just high school. Then add in the beginning college piece that overlaps. So much to do and so many decisions to make. It's draining. I just lived it, with twins, and I'm wiped! I can't even imagine what it would've been like having to deal with a wedding as well. I think, as a pp said, that as parents, it's nice to be able savor each ceremony/rite of passage/celebration, fully, a little at a time. If it doesn't work out that way, well, fine, but one could probably expect that the stress factor would be increased and the enjoyment factor decreased for many. Some people can roll with it, which is great; and some people can't as easily, I guess. So individual.
Yes, now that I'm a mom, & our DD is nearing high school graduation, I really can't believe we scheduled our wedding for the month before my sister's high school graduation.
My mom handled it w/ grace & never really said anything at the time, but, like I said earlier, 21 years later, she'll still say things like, "I can't believe you did that to me!"
We got married in early April. My sister graduated from high school in late May.
In my defense, April was a special month for us - I just didn't pick it randomly. LOL! I actually wanted our wedding to be on 4/1, but mom did voice her objections on that & said we couldn't get married on April Fool's Day. So we "settled" for the following week.
Two weeks before we got married was my sister's senior trip to Colorado. My dad went w/ her class as an extra chaperone. The week after we got married was national competition in South Carolina (academics, speech, etc.), & my mom went w/ my sister.
4 years later my sister got married, & my mom was much more involved w/ the wedding planning. My parents funded most of our wedding, but the planning & preparations were mostly left up to DH & me. Now I understand a little bit better.
Anyway, regarding the OP's situation, I think a wedding, while it unites 2 people, it also brings 2 families together. And, as long as one family isn't irrational or crazy, consideration needs to be given to both families.
The bride & groom need to ultimately do what works best for them, but to only consider one family seems a bit selfish.
I know there are people here who hate their inlaws & come to these things "colored" by their own prior experiences. Still, as a mother of 2 boys, I don't like how there is so much disregard for the groom's family.
I love my sons as much as I love my daughter. I want to be involved in their weddings equally.
Again, I would ask the OP - How would you feel if the situations were reversed?
