["Hey, how's it going? I was just thinking about my highschool days & I got really emotional.", 'Aw, really? Was it a long time ago, or did you graduate recently?', 'Oh, it was a loooooong time ago, actually. I was just remembering all the good times when I was a cheerleader, all the games we won & lost & all the great friendships.']
I graduated a long time ago too -- 1985. Those were great times for me too. I feel sentimental about it.
When I think about my high school days it can really bring up some fond memories.
