How Was School Today?

Like Big Daddy Autism, I have a hard time finding out what my son did in school. He rarely volunteers information, and when he does, it's unreliable. If I ask what he did at school, I may or may not get an answer. If I get an answer, it may or may not have anything to do with school. If it has anything to do with school, it may or may not have anything to do with reality.

He has recently learned to lie, but his lies are usually so absurd no one would believe them. On the rare occasions he hits on a believable story, given his record, we are still skeptical. But once in a while he tells the truth, just to mix things up a bit. And he does some strange things sometimes, which he may or may not realize are strange and may or may not tell us about.

Here is an example of a conversation we had about an event I'm pretty sure never occurred:
PB: What did you do in school today?
GL: I went to the gym.
PB: What did you do in gym?
GL: My teacher made me do push-ups and sit-ups until I threw up.
PB: How many did you do?
GL: Four.
