It's just sad

I came back today to uni from Easter break, and literally no one asked me questions about how it went. My roommate had her birthday yesterday, and I told her wishes, gave her a present, and asked how her Easter and birthday were. She asked me no questions. Same with other people from my course. They know that I went abroad because I posted it on IG, and still 0 questions even though I was asking them about their break. I know we're not friends, but it's still sad that no one shows 0 interest, and they only want to talk about themselves.
