Seems a lot seem to expect just because they like something that EVERYONE should.
It's ok for people to dislike what you like in life. It is not hurtful for them to do that, it is being honest about who they are.
That is what makes us unique individuals.
Expecting everyone else to do and see things the way you do will only end up with you feeling frustrated.
It is probably not what they view as important in life. That is OK too.
