Sarcasm Lost

It's a bummer when sarcasm is lost in a generational gap. Yesterday I asked Faith to bring me the dishes from the living room, she said there weren't any and just kept doing what she was doing. So I come out to the living room knowing full well there has to be a sippy cup or something. And of course there are dishes everywhere, cups, plates, the popcorn bowl, etc... I asked Faith, "Did you look with your eyes open, or were you using the force?" She looks at me with those honest blue eyes and says "What's the force?" I found out sarcasm isn't so great when the recipient doesn't get it....
