Hey, you should knock before comming into my room!
Just because we live in the same house, that doesnt mean you can just barge in here anytime you want.
I could have been getting undressed for all you know.
Well, as long as your sorry, i guess i can forgive you this one time.
Thanks for letting me and my friend rent the two spare rooms in your house by the way.
Is there anything i can do to show my appreciation?
