I think I just jumped to the ADD thought because lately it seems like lots of people I know have it or their kids have it for even the smallest things.
For example my cousin has a hard time processing what people say the first time, so he says "What?" a lot or asks people to say things again. His girlfriend thought he had a hearing problem and when they went to the doctor they ended up saying he had ADD and gave him meds for it.
I know a lady from school who got her kids put on something because they weren't answering to their names being called etc while they were doing anything else, like they couldn't multitask.
