why

Ok, so I got my first "why" this morning. Jayce is not even two yet! I thought I had a few years before this started! The conversation went like this:
I was undressing Kaelyn from her PJs and turned to Jayce and said:
"Jayce can you please put Kaelyn's PJ's in the hamper."
He looked at me and says "why?".
Without a beat I told him "Because they need to be washed."
He goes "OK" and takes them from me and puts them in the hamper.

I'm guessing the future conversations are not going to be resolved that easily~!
