Do you or would you care what your partner / boyfriend/ girlfriend does for a living?
I don't and I'm in late 30s. I probably was judgemental in 20s. For no reason, just false assumption, like thinking trades people earnt low money, which isn't true.
Another example, someone might be embarrassed if their boyfriend was a bin man or bus driver.
Once you have the initial conversation s out the way, I don't think it matters at all.
It's not like your going to work with them.
(If you are that's another conversation)
