I knew what you meant, Rols. I as actually going to comment, but got distracted. It's been a long week, and I'm very vague.

There are the people who ask, and it's ok. If there's that established closeness and friendship there, it's fine. Most of the time, those people don't ask every freaking time they see you! They often wait for you to volunteer the information as often as they ask. And you KNOW for sure that there is a true friendship there.

Totally different to the random work colleague that you would never see outside of work (unless by coincidence or forced into it), who seems to do it every time she sees you without students or other teachers around!
