I occasionally get compliments as: "good job", "Good Catch" from my boss at work. Usually, they send text via text applications. I always wonder whether I should say thanks or nothing to such messages. On one hand, I don't feel like replying by "Thanks" as if I'm a child (or maybe I'm wrong), on the other hand, I don't want to be rude by not replying to such messages.
What is an appropriate way to respond when my boss compliments me over text at work?
