where do they learn this stuff...

Yesterday I had to take Cade to Urgent Care. He had a temp. that was averaging around 102.8. It turns out he has an ear infection in both ears and strep throat. However, since we had to go to Urgent Care we were quoted that the wait would be about 2 hours, so I packed everything I could think of that would keep him busy. Andrew got off work early to make sure Cade was ok and to sit with us at the doctor's office. After about an hour and a half of staying fairly still and entertained, Cade began to get restless, so Andrew got up and walked him around. We were seated right next to the eye clinic so they walked in to look at the glasses and checked out the rest of the building. Andrew and Cade came back, and Cade was just slowly wandering by himself. He started to go slowly into the eye clinic, he turned around and looked at both of us for the "ok" or "the denial", I told him "no" and to come back, but he just stood there. So then I said "Cade, back up, back up, back up". Which always prompts him to walk backwards towards us. But as I said it Cade started to say, "back up back up back up", he then turned around, faced us, and walked backwards into the eye clinic.
