My half brother that i never met added me on facebbok!!! plz read!?

I am sure he know who you are thats why the add. I would accept his friendship he is family after all. Now this whole mess with your mom his mom and you guys dad isnt EITHER of your fault so why not have the friendship. Its just Facebook friendship to see how it goes worse cause senerio you delete him later no big deal, but if it does work out hey you got a little bro man. :0)
