I am not on Facebook. I've thought about it mostly (okay, only) when someone I know says to me, "You should join Facebook!" Then I dismiss the idea and forget all about it until someone mentions it again.
This evening, though, my son told me my other son is now on Facebook. So I'm thinking of joining, just to be his friend. Does that make me a stalker? (I got texting when he moved specifically so I could text with him.)
