Why cant I start a conversation with someone?

Yur talking, like all the barely clad ladies who send friend requests from foreign countries?

I wrote on my homepage, an open letter to them; if you can't prove you're related to me, buzzzz off.Or something like that,lol. Cuz, you know, if she's a niece or a cousins kid, I might reply.
but yeah, that kindof thinned the herd. I couldn't believe, when I first signed on to FB, how many beautiful and well built ladies wanted to be friends with little old AJ.
lol
And like two guys. Strange guys... I mean strangers.
New meaning to the kids phrase "danger/stranger".........
