I understand.My dad is gone most of the day and when he gets home I happen to be done cleaning.So he thinks I havent done anything all day long and he will call me lazy or something.I just laugh it off.
Get out the old camcorder and record yourself while doing the chores. When your dad complains, show him the recordings.
Does your dad have OCD??? Some people you can never please. So how about you keep doing what you are doing and learn to ignore his crappy comments. Otherwise you could tell him exactly how you feel, just as you have told us!
you know the truth just ignore it
