I was sure about the first one that you have spoken the truth because you don't live in Dhaka.
Was a little bit confused about the third one because I don't think you could just reject the proposal of signing and left the place instantly, you may have rejected but leaving the place and sitting on the bus alone seemed to be a lie or unusual.
Well, I got the answer from the comments yet I would have stuck with the third one.
I usually have few friends so I don't hangout much, and also I'm not a social person and hate crowds. So I try to avoid that kind of situation. Thanks for the first guess.
