After living in a different language and culture for a certain period of time, there are words that become your favorites. Maybe because it rolls off your tongue easily, it sounds good, or maybe you just like how it's spelled.
One of mine is "Genau", the Deutsch expression for correct or exactly.
Nowadays, when in a conversation with my boss, co-workers, etc., I try to suppress blurting out "genau". I don't know why. It's a confidence thing, but still, I should use it more often.
