Is it normal to not care about what other people are doing?

I'm the same way. but to be polite I've started asking people personal questions.. now i need to work on actually listening to their answers..

People don't give a shit about people who never show an interest in them.

Human condition.

Introversion. It's the best thing ever.

I suck at this as well. Most trolls suck at it in all honesty.

Nawh, I like to know about other people and their lives even though I know that I talk too much. I don't know why but listening is much easier than talking so I try to listen as much as I can.

I care immensely about peoples feelings, but I don't care at all about the conversations. I prefer not to have too many. They usually bore me. Unless there's a point.

Oh dear. As a friendly nation, the first thing we say to people is, "Hello, how are you?" Or "Hi, what have you been up to?"

In return they either say, "I'm fine!" or "Oh, not much."
They're unlikely to go into long details.

I met a guy every week in the bar for 6 years. He eventually realised he knew nothing at all about me. So he asked my surname, if I was married, if I had kids, where I lived, etc - it took him 6 years to realise that I only ever ask about other people and never volunteer information about myself.

But, I do genuinely like and care about other people, and try to help them if possible.

nah its not all that bad. if i dont want to know about someone then i dont bother asking. generally the people i dont care about like to share all their personal information with me anyway then i have to sit there and pretend to listen to their boring life details. however i will ask about someones life if i genuinely want to get to know them and socialise with them more.

I don't really see it as a bad quality. Asking about someone's life is a polite gesture but lacking in decorum isn't a bad thing, unless you don't have any manners. As long as people you talk to others and aren't afraid to engage in a conversation I think your social skills are fine.
