Being a manager is not benefiting from other people's work, is to try my best to eliminate barriers so they can do their best work. That includes making them comfortable in the work environment. When you reach a point where you work with many people from different backgrounds, you really have to learn to adapt to people and accommodate to their ways of working.

If that means that I don't get triggered when they leave me a "hi" and never come back, that's fine by me.
