I love my brother a lot, but I've noticed that he's not very socially capable. He's very over confident, and doesn't adapt his approach at all for different audiences like most people do. This means that some people think he's a great lad but I get the impression that some people think he's an absolute dick. He is very thick skinned and doesn't notice this himself as far as I know. I feel sad about it and feel on edge when I'm around him and other people. I feel really protective over him but also embarrassed by him. Aibu to be so oversensitive on behalf of someone else or do other people feel like this too?
