How does it differ from that of libraries?
Edit: How do you feel about people who ignore you? Say they can't see you because they have to do homework or whatever, and then they go out with another friend? Is it entitled/a form of nice guy-ism to feel upset about those things (check out this post for more about atypical nice guy-ism...i didn't write it)? What about wanting an explanation for why someone has cut off contact with you or is upset with you?
