Remember Me?

I went to an engagement party yesterday for friends I haven't seen in 15 years!   There were other people from college there and I recognized a few of them and none of them recognized me.  Now, I don't blame them; it's been a long time!   I just think it's funny that I could remember them!   So, I went home and scoured my old yearbooks and a few things clicked into place.  Of guy was a math major like me.  Ah ha!  Another lady lived in my dorm.   It's all becoming clear.
