So it turns out his little "I nee new shoes" trick works for other stuff, and he knows it. I was in the toothpaste aisle. He asked for a new toothbrush, but I bought a 5 pack last week for him so I said no. He started crying saying his teef would fall out because he no brush teef!!
Yes, he got a toothbrush, but only because there was someone else in the aisle giving me the evil eye.
