There's a lot of signs there for toi that some people just don't care about toi that much, ou maybe toi have all the wrong set of your online friends. On this site, there are some ways for toi to tell if your Friends are really your Friends like they say.

Some people on this site never read their mail, others never add anyone back... It's not your fault, so don't take it so personal, okay?
#2 They're never around to comment...
