Last night my daughter was playing a Wii game (My Sims) where you have to build these houses for these people in your town. One guy wanted an arcade before he'd move in. So off we went to build the house for him.
When we were done she asked me, “Daddy… What’s an arcade?”
I spent the next 30 minutes explaining to her that, no, we didn't have the Wii or XBox or computer games when I was her age, we went to the arcade and played video games.
The part about dropping quarters into the machine REALLY boggled her little mind.
