. . . is when he goes on the church youth mission trip and sends you text messages instead of calling home.
Don't worry, I am very thankful to have gotten the texts, because when I sent him to Centri-Kid with a pre-paid phone card (before he had a cell phone), the phone card came home with the same amount of minutes as when he left with it. :-)
I think I'm just jealous that he can text faster than I can (but I can type faster on a keyboard!).
