Boring Post for Saturday--Yeah

My grandson is 2.  He is such an easy kid in so many ways that it is sometimes startling when he does something two-ish.  The other day he was touching the air purifier by the parakeets as he sometimes does.  I did the whole no, no explain it thing about why we didn't touch the air purifier.  He went back to it a few times.  I was finishing my lunch and he wanted me to come play, but I wasn't quite ready.   Finally I said No loudly and shook my head.  He didn't like that.  So, the wheels turned in his head, he walked over toward me and nodded his head very deliberately while he said "Yeah." I count that as our first verbal argument.
