How about I wore them for two days in a row?
Really? Are you going to wash them now?
Yes, I don't want to smell bad.
It's understandable that you are concerned about the smell of something that may be dirty. It's good to practice good hygiene. You shouldn't wear clothes that are dirty or smell bad.
I know that. I don't like to feel dirty and I don't like to smell bad.
I'm glad to hear it. Being clean and practicing good hygiene are very important, both for your health and for your interactions with others.
