For my 60(th many years ago now), my adult children had made all the arrangements, hired a hall, arranging food, photocopied my address book and contact virtually everyone in it. I was told I was going out for a meal with my two eldest daughters and we had to stop off at that hall to leave my year old g.son with some friends who were there.
Went in and there wee about sixty people saying Happy Birthday. Wonderful surprise, and I was so appreciative of all the arrangements that had been made by them. Sadly itg was the last birthday attended by my youngest child who died in a tragic accident nine months later. Makes those memories even more nostalgic.
Twenty years later, my 80th came just as they were lifting the Covid regulations. Originally I had made it clear that I really wanted for that was to be with all five adults children and eight grandchildren. Not much chance in June 2021/
Collected that morning by daughter and family who lived close by just to go out for a lunch, drove for miles and miles (It is really nice place we have chosen - I was told). Arrived -and there were all my children, their partners and my grandchildren. Wonderful, wonderful surprise and so very welcome.
So, just be grateful that you have family and friends who are happy to attend your birthday and welcome the surprise party.
