Learning on facebook

I am using facebook from time to time, I just try a few times to upload pictures on it. Seems like facebook is easy to put up picture. I am still learning and I have many people request, some total strangers. Well I think mostly will be rejected as I don't like being spam. I have got inbox filled with something which I not even understand.

I think I am getting old as I have lack of energy in taking part in challenge contest. I am exhausted and the hot weather making me nuts.
