He asked me while I was in the middle of responding to a paper I was grading, so I said "hang on, and I'll help you as soon as I'm done writing this"
I finished and said I'd help and he started waffling about the whole thing, and I wanted to know if he needed my help or not.
And then this happened:
ME: Do you need help on your Logic homework or not?
LIL' BRO: No, I mean, I don't really, I, uh...
ME: Mom, I'm happy to help, but I'm confused.
MOM: Cam, did you need help or not?
LIL' BRO: Ok, so I don't need help on my homework. I just get a ton of stuff wrong, but I don't need any help with Logic.
ME [thinking]: And here we see the problem...
[Incidentally, this is the same boy who did surprisingly poorly on an IQ test. He was quite defensive about it:
LIL' BRO: No, It's not that I don't have a high IQ, but you have to answer a lot of the questions, and you're supposed to just skip ones if you're stuck, but I refused to skip any, and I got stuck on one in the beginning, so I didn't answer any of them.
ME: Doesn't that say something about your IQ?]
I love my brother. :-D
Disclaimer: Just in case you're wondering, I think my brother is intelligent. But he is also a 14 year old boy. And therefore hilarious. :-P
