Topic: Do you prefer to spend your free time with other people or alone?
It depends on how close I am to other people. But personally, I prefer alone because I can really do something I like. But with my friends, it's another case. My friends usually ask me out for shopping but they spend most of the time looking for what they like and don't care about others. I like to browse in stationary shops but they are not interested in so they would ask me to leave quickly. I don't like that, and I don't see the point to hang out with them. So if I shop on my own, I can look deeper at what I like. Another point is that I feel tired easily. If I'm tired, I can take a rest anytime. But my friends are always full of energy and don't let me take much rest. That's a torture for me rather than enjoying time with my friends. To stay with my family members is much better because they always consider me.

They expect you to help them with their shopping but don't want to do the same for you. Is that right?

I don't think "they just want to see things they like" is the same as "they want you to help them with their shopping but don't want to do the same for you". I take "help someone with their shopping" to mean that you go with them, perhaps help them choose something, then maybe carry it to their car/to their house. It has nothing to do with whether you like the products or not.

How about on your own?
