Is tricking my mom a good thing?

          For my experiment in psychology, I wanted to see if my mom saw something different either of me or what has changed around the house. So what I did was if she kept nagging me to do something, i would just not do anything. But if she doesn't like bug me about something, then I would do something good like clean something in the house or put something away in my room. So for the past three day that I did it, I started to not do anything...being a couch-potato and playing the wii. My mom didn't know what was going on. Her behavior was funny because she sometimes never do cleaning or put anything away.When the day that I was going to start the experiment, we were going up north to celebrate my grandpa birthday. When we were about to leave...I wasn't even ready to go. I didn't do it on purpose, I did it on an accident.

On those days...it was OK. I did do homework,but not all of it. I told her that it will be done by Friday. It was one of those day that I was at home while my mom was out getting things for the house. Before she went she told me that my part of the was such a mess. Anyways, she told me to pick up my clothes before she comes back. When she came back...again I didn't put them. But eventually I did do it. But what did surprise her was that I did my dishes. I do my own, she doesn't see that often when she is not there. But I remembered to leave the computer on because she told me that she need it to use it to check something.When I did some good things, she though I was going crazy or though I was feeling OK. And everyday she thought what was going on with me. She thought it was a trick that I planned on her. But when the experiment was over, i told what I was doing and why. She just gave a little love tap on the arm and she thought I was a good sneaky person.
