re: How old is too old to go to prom?

I remember at my senior prom, some girl got her karate instructor to walk her out.... It was weird. 40+ year old dude with beer gut walking out a senior. But The year after I graduated HS I had to go to my gf senior prom, we had been dating for over 2 years at the time and I was't going to let her go with some other dude. It wasn't that weird for me cause I knew all of her friends and their parents for the most part.
