Rant about ungrateful people

I was at work the other day and I was talking to a girl around the same age as me (we're both young like 19-21) and she shared with me that she had gotten pregnant not to long ago and was happy that she had a misscarriage!! I was so hurt and mad but I just sat there an listened. I have had 1 misscarriage and even though I wasn't ttc at the time the word happy never came to my mind! I'm so upset about this because Feburary 17 would have been my little babies 4th birthday:( and now that I am ttc I can't! We've been trying for 5 months now. I just can't believe that someone would feel that way!
