"I don't feel very well"

The phrase "I don't feel very well" will be heard in our home at least a million times a day by Kellen. He apparently picked up on the fact that when he's ill, he can pretty much be lazy and get what he wants. So, now that he's been fully recovered for months now, he continues to use the phrase before asking for something. It's also said with a big whine, like he's in the greatest pain imaginable. He got us a few times at first, thinking he was really sick, but now it's just like the little boy who cried wolf. If he really is sick, we won't believe him.

For example:
I don't feel very well. I want to watch Elmo.
I don't feel very well. I want some milk.
I don't feel very well. Can I go over to ___ house?

So, apparently he thinks that by using this tactic, he'll get whatever he wants...but he doesn't. So, what we can't seem to figure out is why he keeps saying it over and over and over. Some day he'll realize it's not getting the desired result. Gotta love him for trying though.

P.S. Our camera got sand in it from our California trip. Hoping for a miracle so I can catch up on posts.
