I'm in my 40's and have never gone to one of my own.

It's pretty simple. I had one really good friend in high school and about a dozen friends I hung with often. I was in the rebellious out group and didn't really like the vast majority of the people at my high school, and thanks to social media, I already get to see how boring or train wrecky their lives have become if I ever get curious.

So there's just no need.
