I called my best friend today to wish her a happy birthday.  She said that I was the first one to wish her a happy birthday (other than family) and was glad to hear from me.  I asked her how her day had been, and she said that she had to work today.  She said her feelings were hurt because last week one of her co-workers had a birthday and the co-workers threw a party for her, but no one at work acknowledged her birthday today at all.  I felt really badly about that because she is a really good person and does not deserve to have her feelings hurt like that.
