I've noticed lately that I substitute "excuse me" with "I'm sorry." I'm not sure when this started, but I do this quite a bit throughout the day. It's not even an appropriate saying for what I'm meaning. This is a habit I'm determined to break, there's no need for me to say "I'm sorry" when I'm reaching over someone to grab a straw.
I also noticed other women doing this. There’s no reason for us to be apologetic for trying to get somewhere or something. Is this something we’re taught? To apologize for no reason?
