I remember when movies came in only two D's, and we were grateful for that many!
I also remember when having a cell phone was weird and pretentious and a little bit douchy, at least for college kids who knew their schedules months in advance and could afford to be ten minutes late to the feeding trough or beerpong game. Now I don't even have a landline.
Here goes a chain reaction, but I remember when gas was 75¢ a gallon & cigarettes were 79¢ a pack. This was when I was 15, shouldn't have been either driving nor smoking.
