What do you think about me liking the smell of my own farts?
Why do you like the smell?
I like it because nobody knows its me farting, and I like my own brew.
If you want to sniff your own farts you should not fart around other people. People would be grossed out to find out you smell farts and enjoy them.
I don't care what people think I smell like.
The problem is that you are being inconsiderate by passing gas around others. Doing this will cause people to avoid being around you. It's best to excuse yourself instead of doing it around other people.
