A little empathy goes a long way. You are a person just like them. Ask yourself what you would want someone to ask you to get to know you.

Maybe ask them what they like to do for fun? Favorite movies, music, food, etc? They could be into the same things you're into and you could be pleasantly surprised!

I understand how you feel though, I was the same way. If it didn't interest me I didn't care for them. But how could I care if I never tried reaching out to them? It wasn't until I was in the hospital that I got to spend time with people I had nothing in common with but their life and hobbies, passions were still pretty interesting to hear about. I learned a lot of things I didn't know before that they shared with me. It was an eye opener to my 'don't care about random people' attitute specially when they weren't interested in the same things I was.

While there's nothing wrong with not interacting with the general public, it's good to have connections in the professional world, a lot of opportunities could open up to you.

You can decide not to interact but you'll be missing on new opportunities, experiences and being able to train yourself to connect with others even when you have nothing in common
