Oh Please don't yell in the bus~

One day I was coming home after work in a public bus. I heard one woman is yelling, I looked at her, it was look like she was talking to herself, because I didn't see her phone, or earphones. People around her looking at each other, nobody understand her because she was talking in foreign language. However I couldn't wait to get out of the bus because even I didn't understand single word she talked it was annoying to everybody. I think biggest problem is her both ears were pluged and she doesn't know how loud she was. I think people like her should learn to respect others in public places keep the private matters to their own home.
