I'm an extreme introvert and engaging in small talk was exceedingly difficult when I approached it thinking I had to be the one to initiate conversation. Cause I'm awkward and really bad at it.
Same here, only problem is that most people are ignorant and instantly assume because you're quiet that you're arrogant. I've found this out over many years and can understand where people are coming from but at the same time it's like people are stupid and don't realize some people are shy, or just don't like to talk a lot all the time.
Also, conversations get a lot more interesting when you get to the meat right away. I find talking to older folks to be much more interesting than talking to people my age or younger, because most older folks will just say what they mean, right away. No "small talk" or "putting on appearances."
In my experience it's also because older people have better stories and are in a lot of cases more intelligent than teens and people still immature in their 20s who talk out of their asses.
All that stuff is MUCH more interesting than talking about the weather.

As introverts, we're actually better built to get to the real meat of a conversation and find out more about people.
