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 *****y, 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.
