Are You Flirting With Me?

On the list of things that Sai does at this age, I would like to add, smiles at strangers prompting them to say, "Are you flirting with me?" ... Ok, my response, "Whatever lady" .
What's with that? Do you think you are so special and beautiful that babies "flirt" with you? Several people have said this and it seems to be the norm, but I don't get it. What if he were 5 years old or 10 and smiling, would he be "flirting" with you then? Uuhh no. And what if I had a girl and some crusty old man said, "Are you flirting with me?"...creepy. Sure, I want him to smile, we all need more smiles in the world. And maybe, you are just trying to be nice, and maybe you don't know what to say, and that is the socially accepted thing to say to a boy baby that is smiling at you, but here is one person that thinks it's a little weird. I would also like to ban "Lady Killer" and "Heart Breaker" and "Pimp Dog", all of which I have seen on baby t shirts. So, if you see this face at the grocery store, just say, "What a happy baby you have" or "What a nice smile" or "Can't you make that screaming baby stop?". Thank You.
