Excuse me, what exactly does this mean? What kind of stalk is this?

If used in spoken English: I'm sorry to disturb you, please forgive me, sorry, excuse me, excuse me, etc.

If it is used on an expression pack: Are you kidding? Your expression is helpless and a little contemptuous.

I'm sorry, but I have to go now. ? Sorry, I have to go. ?

Please forgive me for interrupting you. Excuse me for interrupting you. ?

Please forgive me for providing you just now. Please forgive me for offending you just now. ?

Sorry, I seem a little lost. I'm sorry, I seem a little confused. ?

I'm sorry, but I want to know what all this has to do with us. Excuse me, I want to know what all this has to do with us.
