I'm thinking if it weren't for my co-workers I wouldn't have anyone to talk to.
That sounds sad, do you like talking to your-coworkers?
Yes, we always have good conversations.
It's nice that you like talking with your coworkers because having a good relationship with them is important for job satisfaction. You should continue to talk with your coworkers because it's good for everyone's morale.
It would be nice if we could spend more time together through normal means. My only hang around time is when we're at work.
Well if you like them a lot you can ask if they want to get a drink after work. That way you can find a bunch of people who might want to or invite them to play some online games.
