I like talking about weather; and I agree it's cool (literally, sometimes XD).
I was kidding, thinking about how people make "small talk" asking, "so how's the weather?" or something. I loathe small-talk, period. It's something that's socially awkward, I think.
Then again, I feel socially awkward a lot. Unless I'm with friends or close family. Um, yeah. But I never EVER ask "how's the weather;" I pretty much don't talk unless I actually have something to say, or someone starts talking to me.
While I don't like the scientific stuff about weather, I like observing it. Like when it snows, or watching a thunderstorm, or knowing when there's likely to be a rainbow, looking at clouds, etc.
