Truth Can Be Such A Pain!

When my son is fussing and complaining about schoolwork, i get very aggravated sometimes. Often i decide whatever plans i had with him are shot, forget it, i don't want to be in the company of someone with such an attitude.
Today i just left to run errands, ignored the places i had planned to stop for his pleasure; i even decided to deliberately bring back the remains of a fast food lunch so he would see what he missed because of being such unpleasant company. But as i was driving, fuming about how i don't even want to go to the trouble of raising him if he's going to be so obnoxious about doing his own work, work that's for his own good (not that i really expect a child to understand that), something struck me. Hmm....

1. He complains about doing annoying schoolwork.
I complain about doing annoying child training.
2. He complains that he has to put so much effort into his work.
I complain that i have to put so much effort into my work.
3. He complains that he can't see any result from so much effort.
I complain that i can't see any result from so much effort.
Unfortunately the list can go on and on and on...
WHY do children have to be such perfect mirrors?!
