Why is nobody happy for her?

My sister has always wanted a baby but the doctors told her she had a slim to none chance of having one. She's griped & moaned about why is this or that girl having one. She always would say, "well this girl is a slut or this girl isn't married why can't I have a baby I'm ready." Well she's divorced & pregnant with a guy's baby that he doesn't want and they were dating for like two months & he left when he found out. Now she's mad everybody isn't over the moon happy about her baby. All that hatred & she's in the same boat as the other girls maybe that's why people aren't as excited. I guess I'll take the high road & not tell her karma sucks because this may be the only baby to ever be in my life. 😑
