I used to do this, but I’ve evolved to explaining my biggest weaknesses and how I cope with them. I try to be earnest about it instead of pretentious; not a humble brag, but a moment of genuine vulnerability.

I don’t like answering shallow questions, so unless I’m trying to get something from the person, this filters out people who care too much about normality to every like me. I’d always mess up and reveal myself to be a weirdo eventually, so I might as well save their time by not pretending.
