"He was so egotistically confident in his own sense of humour, and his judgement of mine, that I don’t think he noticed I wasn’t actually laughing." Oh my gosh, I know people like this. They sit there and rattle on so amused by themselves eventually I end up laughing not at their jokes but and how oblivious they are to the reality around them.
It sounds like you're ready to rock anything. Taking no bs or taking names! And there are entire communities out there based on scar fetish. That thing making you feel so un-sexy has literally hundreds of people jonesing after it! It's the same rule as with money and power, whatever you've got, somebody wants. Just sayin'.
