It's strange. You would never describe yourself as a jealous person. A woman could flirt with your husband and you're mildly flattered. Your friend gets a great promotion and you're genuinely happy for her.
But when someone gets pregnant, whether a friend or a complete stranger, you're jealous, evil side emerges.
It doesn't even matter who it is. You're completely envious of all your pregnant friends but you are also jealous of complete strangers on the street, Facebook friends from your past, your parents friend's children, and anyone else who happens to walk by you that could look pregnant. Good lord, they don't even have to be pregnant to get your jealousy started - you are jealous even if they seem to have an unconfirmed belly budge or if their television character is pregnant. You would even be jealous of a woman who got pregnant knowing that she suffered through years of infertility treatments. You would be jealous if you're dog was having puppies, Mertie, the bird, got pregnant or even if a cartoon character was expecting. Damm you Marge Simpson! You never had infertility problems with Bart, Lisa or Maggie! You were jealous of the pregnant "man" and wished you could be the Octomom too.
Wow. Bubbles, your goldfish, is having babies. Yup... Still jealous.
