@agilebasenji:
what she said.
At my house a valid excuse for not getting up is, "But I'd have to disturb the dog."
My husband is delighted that Shaye's and Gemma's favorite place to take a nap while we are watching TV is on his lap. Sometimes it works, sometimes Shaye won't let Gemma up there. But the deal is - when a snack is called for, or my husband's thirsty or the phone rings, someone's at the door, whatever, his constant cry is "But I have DOL!" which, of course is "dog on lap" so it falls to me to get up and tend to everything. Grrrrrrrr. Occasionally, Gemma will sit on my lap when Shaye is snarky with her - then, of course, I have the larger DOL, so he has to get up. It's a game with us. I usually lose.:p
