Let's Roll

I was playing cars with Alex before dinner and he piled a few into his Mac truck and said, "Let's roll!"
Totally random because I have never heard him saying that before while playing cars. I *think* he got it from the Cars movie...

Another thing he was doing was pulling up his larger car (it's bigger than matchbox cars) up hood to hood with the smaller matchbox car I was told to drive and would say, "Hi. I'm the big car." "Hi. I'm the little car." After a minute I caught on that the little car line was mine. After I said my line, he would say, "Let's roll!" and we'd drive off together.

We pretty much think that cars and the road rug (from Ikea) is the greatest thing ever around here (both parents and child think so).
