What are you guys like at work?

I prefer to keep myself to myself and just get on with my tasks. My coworkers are lovely people don’t get me wrong, but I don’t really see there being any necessary reason for me to be social with them. I only speak to them if I’m spoken to and even then it’s mostly just small talk. Work is just a way for me to make money. I’m literally only there because I’m getting paid. Unfortunately I don’t even get paid overtime so if they asked me to, I’d refuse instantly. I don’t wanna be at work for a minute longer than I have to. But it makes me curious to know what other people are like at work? Do you guys just keep to yourself and get on with it or do you actually like mingling with coworkers?
