i love it when...

I'm grocery shopping (and totally minding my own business) when a mom will walk past me with her baby in the shopping cart and the baby looks up at me with a HUGE smile and says, "Hiii!" Those babies just seem soooo happy to be out and about seeing new people and trying to grab all of the items on the shelves. I think it is adorable, but it always makes me wonder what the moms are really moms thinking. Some moms will smile at me once I pause what I'm doing to smile and say hi back to the child. Others give me an apologetic look (I'm not sure why they would be apologizing for having a friendly child). And others just seem annoyed.
