In my view, nobody should touch other people's babies - or kids - uninvited. Hell, that even goes for my cats. It does happen a lot. If it's little kids I am harmless about it. If it's adults, I am not. I don't know what's behind it. Cute, small, and defenseless?
Puzzled that you are having a swine flu problem again. Since when? Hope all of you won't catch it.
