So difficult child is doing some math. He gets stuck on 8+6, which is something he should know. So husband says "You've already done 8+5, so if you add one more..." and difficult child shouts "It's 14--I know! I don't need your help!" (Even though he had just told us he did not know what 8+6 is, so he did need help.) So husband is like "Correct, it's 14." So we leave the room to let him work by himself because he "doesn't need our help." A full 10 minutes later difficult child comes into the living room and says "I don't know what 8+6 is." I said "8+6? Isn't that the one we just helped you with?" He says "No--you didn't help me with that one." So I went to his math book and he was still on the very exact same problem we just helped him with where he shouted out the answer. And I said "Yes we did help you with that. remember, we looked at 8+5 and added one?" And difficult child was like "Oh yeah! It was 14." We asked him why he didn't write it down 10 minutes ago and he said he didn't know. So basically he just daydreamed for 10 minutes and totally forgot we had even discussed 8+6 or what the answer is. But nooooo....husband refuses to believe the boy has ADHD. It's frustrating.
