if u think they are, then they are, if u think they are not, then they are not.
as u may read in this thread much people have diffren opinions about it, some would say no youre not friends, some would say, yes you are friends and some would say, yes you are "internet friends" (if u want to know whats meant by this, read what zayex posted.)

so if u feel that they are friends, then they are ;)
