Shocking

I never knew my family on my father's side.  A few years ago a first cousin contacted me on Facebook and asked if we could be in touch from time to time.  I told him that was fine to chitchat a little bit.  Well, he wanted to spend an hour a day chitchatting and I just stopped being available.  He wrote me a whiny message and then we talked (on Facebook) on and off for a couple of months.  Then one day he sent me a message asking me to send him nude pictures and promised he would do the same.  Dear God, I have never been so shocked.   I immediately completely eliminated him from my Facebook presence.   What the hell is wrong with people?!?!
