Charging

Imagine you are a little kid.  You walk around watching adults take out little cards, swipe them, and then get whatever it is you want.  Card, swipe, cool stuff.  Isaac sees this almost every day as we are not "cash and carry" folks.  I usually have no more than a few random dollars in my wallet, along with my credit card. 

Well, after watching this pattern again and again, Isaac has started asking for cards to swipe.  He swipes them on everything--playground equipment here.  And this time he tells me what he buys. 


No sure what the high pitched whine is, he usually reserves that for his weedwhacker noise.
