I did the same, I’m polite, helpful and pleasant to be around. I also keep everyone at arms length and am very careful with how I phrase stuff, people in the office love me and understand I won’t be sharing personal stuff and I’m not interested in their personal stuff. If they wanna talk weather, TV shows or games I’m fine with that.
I was always polite and vague with how I declined their questions early on and eventually they got the hints.
