You are a very lucky young man. So go with it. Confidentiality is a double edged sword. So if they are to say nothing about it, neither should you. Keep it out of the workplace.
Look, work gave me my life and has saved it on more than one occasion. And in part its because I (and most of the people around me) feel very strongly in the American sense, that "Nothing personal, its just business." I've had to fire people, or let them go. Nothing personal, it's just business. I've had the same happen to me, and again, nothing personal, it was just business.
It's a real big deal with me that I really don't want to know that much about you other than what affects the work. (Lucky for us, we're union brothers and sisters and union stuff can easily fill 8 hours a day of conversation) but I don't want to know if you have a BF, GF or wife. Or if they are sick or not. Or your troubles with your kids. Really, the best part of work is leaving all that behind for a few hours.
I've had girl scome up to me and say things like "Oh that Tom guy you work with is a hunk, does he have a GF?" And I say "I have no idea, we never talk about that kind of stuff." And we don't. There are people I've worked with for over two decades and I don't know if they have a GF, or are married or any of that. Nor do they know that about me. I like it that way.
So, like the day I was late for something my dad wanted me to do and he told me that 90% of any job was showing up. Like a little smart ass I said "So, what the other 10%?" And he said "Shut up and do the work." I thought he was kidding, but he was spot on. Show up, shut up, and do the work. It's the guy way.
