who needs texting?

Maybe it's just because I don't have teenage children, maybe it's because I don't work in the business world, maybe it's because I just don't *get* texting. I think it's great to be able to send a text to someone who isn't able to talk on their phone at that moment, but when two people sit and text back and forth, that's just, well....wouldn't it be easier and faster to just call them and talk? My point? you ask. My point is that my 5 year old demonstrated her own version of texting. We were in the living room together when she got up and went into the kitchen to draw on the easel. Five minutes later she called me to look at the picture she had drawn.
Wouldn't it have been faster to just say, "Mom, can I have a drink?" I know, asking isn't nearly as cute as this picture :o)
