Brayden's Chore

We've given Brayden his first real chore (besides cleaning up his toys every night). His 'special job' is to make sure the cat has food and clean water every day. We've had to remind him so far and each time we remind him he gets all excited and takes care of his very own 'special job' right away. I wonder how long it will be before he realizes his 'special job' is really a chore and start to complain about it...
