High five, me too!

At that age I also used to do speed run little programs on the display computers in department stores. I'd write a little prompt welcoming a shopper and ask them their name. Then a response that echoed back their name in some way. If I was in a good mood it was "Hi [name]!". If I was in a snarky mood it was "Fuck off [name]!" The goal was to write it in about 30 seconds, before one of the associates came over to see what I was doing.
