I didn't want to go to my first HS reunion (10 years) but my girlfriend came all the way from Canada to go so I grabbed another girlfriend and the 3 of us went together.
I didn't want to go to the second HS reunion (20 years) but my girlfriend again came all the way from Canada to go so I grabbed that other girlfriend and we went once again.
Since then there's been no more reunions. Thank goodness!
However, my DH never went to his reunions until the 30th rolled around and I convinced him to go, we had a blast, they've had one one every 5 years since and we've attended them all, really looking forward to the next one which is next year, don't know why his are so much more appealing than mine - go figure!
