I know some people like that. They hate conversation about nothing because they only want to ramble about what interests them, so if someone asks, "how are you", they don't know what to say.
Exactly why their not good at small talk they get nervous and start to ramble
yes! they can be irritating, it's like they try to trap you into their weave of words.

Wish there were more like them.
