Me (to 11 year old son): You need to get started on your homework.
Him: I don't want to do it right now. Besides, I can get it done fast, like in 20 minutes.
Me: I don't think you can get it done that fast. Come see how much you can get done in 20 minutes, because I don't think you can get it all done.
Him: Mom, stop trying to use reverse psychology on me.
Note to self: Reverse psychology doesn't work on him anymore. Find out what psychology he was using on me.....
