Well, if you really feel lonely, then you should see out of computer, our life is not around on only internet or chat, actually we feel lonely because we are busy all the time on our work and we don't give time to anyone and when we feel lonely then we need people to talk with us. So it is our fault we should balance our life.
If you feel lonely I suggest you to go out and find real friends, not those virtual or imagined.
Life is not only on computer but out there, just waiting for you

You two are right. There's more to go finding enjoyment outside your home. But you can't blame someone on the web who are looking for people to hang out into a chat box because he might be an introvert guy.
