I Care Way Too Much About What People Think About Me

He wants to know why I'm so standoffish. I'm standing here alone while they are visiting. I think I detect anger at me coming from his sister but she could just be really busy and tired. I hate assuming and believing someone doesn't have a problem with me then find out later they did. I feel so stupid when that happens. I said I have a toothache which is not a total lie. His daughter likes to tell people lies about me to most anyone she spends time with. I know this is true because they tell me down road about it. Not all tell me I'm sure. Sometimes they accidentally let it slip. Feels horrible to find out someone is being nice to you only out of manners and actually don't believe you are a good person. Especially when you like them and wanted their friendship.
