Cyber love......

There is this thing that is so common now......you get to meet someone through social network and you guys start dating without seeing the person.Its always so funny to me when someone I meet on bbm or fb tells me that he likes me.........Am always amazed like seriously you don't even know me,how can you say you like me when you don't even know the kinda person I am.Is it just me that thinks its not possible to have feelings for someone you've never seen before.So what do you guys think.........Is it possible to have feelings for someone you've never seen before???
