She wanted to be buried with my father. She was cremated and my sons and I will be traveling over 300 miles to attend. I have communicated with as many friends and family as possible, but have no idea if people will attend. Is this odd? I’m an only child, so everything fell on me.
If its a memorial service with open attendance hours during a few hour window, eg at church, I think its pretty common to not have RSVP requirements and not know how many people are coming, and there is no harm in that. In that situation there is no need to actually know the exact number.
As far as the emotional side of not knowing how many people will attend, or perhaps are you worrying that only a few people will show up? Hopefully you wont worry about that, try not to. Keep it in mind that you and your sons are going to honor your parents, and that's the most important thing. Try not to worry whether or not a lot of people come. Hopefully you will be pleasantly surprised with a good attendance.
Or because she died in May and now it's August before you're doing something? Again, no that's not odd. Lots of folks especially since Covid have opted to delay funerals/memorial services.
Or are you asking if it's odd if no one else attends but you and your boys? To which I will once again say no, it's not odd as you are the most important people that should be there anyway.
This service is more for you and your boys than anyone else, so I hope you just enjoy it however it turns out.
You are doing what you wanted to do, honoring what your mom wanted. That is the important thing. If it is just you and your sons you can still make the most of the trip. If a few or many show up enjoy the visit with them. Have a nice visit, share stories and memories.
When I arranged the funeral for my Husband I had no idea how many would show up. I chose to have the wake and funeral the same day.
I was floored as to how many showed up. the Funeral director said to me that I probably should have had this scheduled for 2 days. I told her that I had not seen some of these people in at least 10 years. (where were they all when he could have enjoyed some of the company early on in his dementia?!)
