Is it too much to ask for a simple yes or no? You were invited, you were thought of. There is no right or wrong to do things anymore. How much one spends is irrelevant too. Don't say yes though and then not show up.........If I invite you over for a Christmas dinner - isn't there a reply needed? I don't get it. Everyone knows if they are going or not wether or not they have the Save the Date or heard of the date by word of mouth. Regardless, if you know you are going, respond. If you are waiting for "something better" to come along, then the people inviting you are not that important so simply say No........If you need an extra day or two.....getting off from work, traveling, babysitting schedule, please let them know too.
It does not matter if it's a birthday, shower, retirement party, wedding etc.
It does not matter if it's in a barn, house, restaurant or catering hall. I might have 20 people and someone else might have 50 people. As a guest.......how do you show up when you were not accounted for?
If one can take/make the effort to invite, call, send an invite, pay for postage......just have the decency to reply. Yes, or no. No explanation. No need to "speak" to someone to make excuses/explain, etc. Whichever way the RSVP is offered, Text, call, mail back the response card with the stamp provided.
Yes or no.
When there is no response - (unless you know it's lost) - it sends a clear message - you don't care enough.
Good luck to the OP. Double check if any got lost. I have gone through this and I am going through the same thing as many others have. I would have the spouse's mom, call for their side.
For anyone who does not agree with this, fine. It's your right/opinion, etc. I don't think someone will understand until they have their own affair. Maybe they will be one of the lucky ones who have all the responses.
Now if you have an open house affair/invite......totally different. Cannot compare to the "norm"
Just my thoughts
Enjoy and peace!
