I'm more of a quieter type, and I always struggle with people who label themselves as 'we're mad us, ignore us, we're a bit crazy that's all.'
I've had a few in different jobs. I imagine they think I'm really boring, I struggle with social anxiety and I can make basic conversation at work but I just struggle to be like the above.
I usually just laugh and smile when they say stuff like this, I don't really know how to react at all.
