Yeah, i think you're right about reading too much into stuff sometimes.
It only caught my attention because a friend of mines child is seeing a child psychologist and she was saying that they had noticed she drew people without arms and was sure it was significant..
I later glanced at a drawing of our family on the fridge and noticed there were no arms on any of us!!!!
Then i checked out his other pictures and sure enough, no arms. Wierd how i hadn't noticed, eh??!
