Has anyone attended a school reunion

I've heard they're a hot bed for rekindling teenage romances! Probably for those 20 years younger than I am. Shame.

Yes, I’ve been to quite a few and enjoyed them very much.
Not competitive at all, everyone seemed so nice and several old friendships renewed.

I received one about 20 years ago via my Mother, I would be in Scotland at the time and she could just not understand why I did not want to go.
She was a bully and a control freak and did not get that I did not wish to see people who had bullied me unmercifully for my entire school life.
Until my DBF friend pointed out that I had done very well and definately had bragging rights. He is nosey and had done a bit of research on the bullies.
I still did not go, partners were not invited, if he had been with me perhaps !!!!!!!!!!

Yes, I went to one when I was 50. I met up with someone I used to be really friendly with when at school and we have re-started our friendship.

I enjoyed seeing people I had not seen for 34 years although many of them now lived far away so I shan't be keeping in touch.

All in all, it was a positive experience. It wasn't competitive at all and I'm sorry your experience was not good.
