I think people on the bus wouldn't sit near me because I smelled so bad.
Why do you feel that this was why they would not sit near you?
I think it seemed like they were not happy to share a bus with me.
You should be considerate of other people on the bus and should not have bad hygiene in public. Clean yourself before going on a bus.
I was on a bus with a person that smelled and I might have felt uncomfortable because of it.
You should do your best to have good hygiene if you know you are going to be sitting close to someone on a bus. If you are able to, make sure to wash yourself well so your hygiene is not even a topic of conversation.
