I'm sorry is not something that should be said flippantly. It is often used as a filler word, in place of "excuse me" or "pardon me" or to end an argument we just don't feel like having - Sorry,. Not Sorry. Language is very powerful. Use it carefully and save your I'm sorrys for when you really hurt someone and need to honestly say "I'm sorry."
As always, I wish you the MOST from your potential!
