We were standing in-line waiting to check out of a store the other day and Adam pokes the lady's butt in front of us. (In his defense, it was kind of big and squishy looking). As Dave pulls him away to talk to him, Adam kicks her in the ankle! I drag him out of the store while Dave finishes checking out.
Yesterday, we were at a park and another little boy brought a bunch of matchbox cars to share. Unfortunately, Adam thought that meant he could take them ALL (there were about 8 of them). I tried to explain he couldn't take even the one the owner boy was playing with and now he couldn't have any. The other boy's mom came over to take the cars and put them away. She put one in her pocket and Adam went and stuck his hand in her pocket to get it! She said, "Uh, Adam! I don't think that's appropriate!" I apologized and we left shortly after (Adam was given one more chance at sharing and failed).
This is more funny but still a bit inappropriate. We went to a different park after the incident above. There were 2 african/american boys playing in the sandbox and Adam walked up behind them and touched their hair. They either didn't notice or didn't care but I gave Adam the "keep your hands to yourself" speech again. Listening is not his best skill...
