Enraged!!!! Vent needed

If I have to sit and listen to my co-worker 1 more time talk about how she doesn't like kids and she's soo happy that her partner doesn't want kids I think I'm going to slap her!!! I respect that it's her choice but she doesn't have to gloat about it everytime someone brings In their kids or is sick because they are pregnant. Pregnancy is a special gift not an annoyance! Thanks ?
