Nobody is going to change much. I guess everybody has their own thing, then there is the question of whether they should bring their thing to my house. Maybe it isn't so courteous to bring their thing to my house, especially if I already said I'm not really into that particular thing. They can play with their thing, just not at my house.

I think there are two ways of looking at being human.
We are all the same, because we are all share being human and so forth.
We are all different, because we have different experiences and so forth.

So, you hold those two thoughts at the same time and have the answer.
