I hate it when people say “I’m sorry that I’m interrupting you, but…”.
People think that it’s good manners to say that. It’s not. It’s a fake apology. It’s a meaningless saying.
What they are really saying is: “I know that my interruption is out of place, but I will do it anyway because I think that what is in my mind is more important than the rest of your idea and that gives me the right to interrupt you”. They are NOT sorry for interrupting. Why don’t they just own it?
Everyone, whether in authority or not, commits this dickish act. It doesn’t look good. It makes everyone think of that person as an ass.
So the next time this comes to your head, think twice before saying it.
