My wife joins the other OCD posters on this thread: she cleans the house, changes the sheets on all the beds, washes/dries/folds/puts away laundry, scrubs toilets/tubs/showers/sinks, etc., etc., etc. I think it gives her some peace knowing that the house is staying clean for so long. All the while, I'm screwing up the packing ("you mean the baby can't get by on 2 pairs of socks for 9 days?") and forgetting other important things. It's our Disney pre-trip tradition.
