It always seems like my wife wants to give me instructions about something when I'm already deeply concentrating on some trivial thing, and I don't even hear what she's saying, let alone remember what she said.
Like right now for instance.....I'm hammering away on the keyboard, obviously doing something important, and she starts to tell me about some plant in the garden that she just watered because it was looking a little sickly, and that she didn't want me watering it again today because perhaps it was sickly because of overwatering it, or some such thing..
