Two things I think are great surprises for myself.
1. Forgetting that I folded all laundry from the dryer, go to do laundry, open the dryer and find there are no clothes to fold. Score!
2. Forgetting I cleaned out the dishwasher, go to get ready to do the daily, unexciting task of cleaning out the dishwasher just so it can be loaded again, open the dishwasher to find it only 1/4 of the way full of dirty dishes! Ahhhhh bliss.
Either I'm becoming forgetful or I'm in such a sad state that an empty dryer and barely full dishwasher become such exciting things that help make my day.
Probably a bit of both.
