<human>: I started a new job a few weeks ago working in the IT department of a company. I am the first girl they've had there in years, out of around 10-15 guys. 

It seems like most of them are friends with each other, hang out outside of work, and talk about their lives outside of work amongst each other. I feel quite excluded from these conversations, and no one really talks to me except if it's about work, and when it's not, it's just a few words.

I would say that most of them are pretty sociable and not awkward, unlike your stereotypical computer nerd. I would say that I am pretty friendly and have been doing a good job at the tasks I've been assigned. I am in my early 20s and they are in their late 20s - early 30s, so there's not a huge age difference. I really can't see what the problem is, except that they just don't see me as "one of the guys" or someone that they can be friends with.

What should I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: version: I am the only girl in all-male IT department and I feel like this:  Not sure what I should do.
