People never sit next to me at the bus, I guess I just show off that I don't want someone to sit next to me, in case, I'm not really thinking like, Oh, come sit here, It's hard for me to take the bus, because of my SA, so people probably see it in my eyes, I think that's why. People just don't want to make me feel uncomfortable, or are probably scared by my attitude, it's a matter of not caring about their not sitting next to you, it's not a shame, I know you can get thoughts like, why?, am I weird? actually, people are weird. Everyone is, so don't blame yourself, don't blame anyone, and always remember about this, it's not a shame if I don't have someone sitting next to me, because these people will just go and leave, you probably don't face them everyday, so they are just strangers, if your family or friends would not sit next to you, that would be a serious issue, that is a fact, try to not worry to much about it
