Can I take a shower once I get there?
Why did you take the shower so quickly?
I just wanted to feel clean again.
It sounds like you have good personal hygiene. That's a good thing. If you hadn't taken a shower, people might have thought that you were stinky.
I'm not stinky by the way. I'm a person who loves to clean things.
That's fine, you don't have to be dirty to care about your personal hygiene. It's always good to want to take care of your body by bathing.
