Time to feel really OLD.  Here are seven things you'll have to explain to your kids one day.  Enjoy . . . then cry.

#1.)  How you used to have your friends' phone numbers MEMORIZED . . . and why you used to have to talk to their parents sometimes when you called them.

#2.)  Why we used to buy maps, and how they were so hard to re-fold.

#3.)  Taking a photo and not getting to see how it came out instantly.

#4.)  Dialing star-69.

#5.)  Taping a song off the radio so you could hear it whenever you want.

#6.)  How the only way to get song lyrics was to hope the band or artist printed them inside the tape or CD liner notes.

#7.)  Smoking and non-smoking sections in restaurants.
