Why do people get their "feelings" hurt?

People can get their feelings hurt or can get offended for a variety of reasons. Sometimes they really care about the person that's doing the hurting/offending, and it's more about being let down by someone they care about. And don't even ask me what disappointment's about haha. Sometimes though, someone just says something that goes against their values or makes them feel like their opinions don't matter and they feel threatened. I hope this helped clear it up a little. I think it's pretty admirable that you're trying to understand something that's really alien to you.
