That picture makes me think of all the people who come and want to talk to me when I'm reading, and then get bent out of shape about how rude I am because I continue reading instead of paying attention to what they have to say. I want to bonk them over the head with my book.

I do think it's rude to start texting in the middle of a conversation[1], but that pic doesn't make me think that's what's going on there.

[1] Mostly because I have yet to encounter somebody who can actually do it. So far every person who has done this has lost the thread of what we're talking about. I might feel differently about somebody who was truly capable of doing both at once.
