You got the moment here, catching not only theyr attention, but even our. I think pretty much everyone who looked at this pic wondered what the boys were thinking, having such a different reaction! Sometime I did give a hello to people passing by while papa was driving in the highway. Funny thing is that sometimes I see kids saluting me now! And as I wanted to be returned I alway raise my hand to them :D So finally this is probably something more usual than expected between human kids passengers!
