depending how old the kid is, it's reasonable to expect them to notice something is dirty and do some cleaning on their own. especially if it's their own laundry or own room. that's what you have to do as an adult, so reminding them that they are responsible for noticing these things is training them.

adult men don't have to be mind readers. they should know what needs doing in a house by virtue of being adults. there's no reason women should be the directors of all housework.
