Quinn was over counting coins. We put the quarters in stacks. We had five stacks. I asked her how many stacks she had and she replied, "Four." I looked at her funny and she explained, "These 4 are my stacks. That one is yours."
Continuing on, we spread all the coins out to count them. I suggested we put them in lines so it would be easier to keep track of the coins she had counted. She said, "Or you can just pick them up as I count them."
I've been out thunk by a not quite 4 year old. Sigh.
