Also, landlines are useless anyway. So if you have that, you should really consider cancelling it, and get a cell phone. You won't regret it.
You should get one. I have very few friends as well, but I probably wouldn't have those few friends if I didn't have something to exchange contact information with. I'm kept "relatively" in the loop of events because of my more social friends.
Landlines aren't useless, how else are you gonna get a 6 Mbps unlimited DSL connection to the internet for $40/month?
I have a Tracfone (pay as u go) cellphone, that costs about $100/year to use. The minutes keep adding up, but it's good for emergencies I guess.
I don't have anyone to call either, so I got a Blackberry and set it up so that I get alerted each time I receive a useless spam email. It makes me feel super important.
I mostly just use my cellphone for my alarm clock. lol.
