I have a friend that chastised me because I didn't call her when she thought I should.?

When I called her she was crying because of a personal problem and we talked for a while and I tried to calm her. I called her three days later to see how she was and she said she didn't want to be my friend anymore because I didn't call her the very next day after she was crying. Now, two weeks later her problem is solved and she called and wants to be my friend again after she severly hurt my feelings and didn't want to be my friend.
