You're not really socializing with people in the office either, you're working with them. Without a boss around looking over your shoulder, you have a lot more time to socialize if you want. Go get a coffee with a friend, your partner, your kid...

I'd also describe the office as anti-social as I would not voluntarily spend my time with the majority of my co-workers and having to be around them day in and day out is extremely draining and demoralizing. I find surrounding myself with people I actually care about and have real bonds with to be far more positive.
