How Do Plan "sweet Revenge" On A P-

Whats the situation?!
We gotta know sums before we can tell you what you could do.

Hey Cheli:
Here`s the 4-1-1.....My sister-in-law from "HELL" is always trying to compete with my husband and me. Her husband and mine are brothers. First they had to get married before us, she had the same colors as our wedding, then....she was pregnant for almost 2 weeks and decided to announce it at our wedding so she`d have something to talk about, the day after our wedding she was "seen" coming from our house when she was supposedly at home sick with morning sickness. She has written and called my former employers with accusations to try and get me fired. My mother-in-law use to be alright, but now she favors this poor pathetic one and I`m suppose to kiss her (sister-in-law) butt at the holidays and play all "nice-nice". I was raised if you don`t like someone, you don`t be "two-faced" about it. Now.........they`ve bought a lot to build a house, which was where we were looking to buy and build. They don`t have a "pot" to dump in and she`s a major credit card junkie. Most people don`t like her, but they tolerate her and are civil to her. We also live in a really small city. Like I said...she`s forever in my face indirectly and whenever she can make herself look better in front of "mommie dearest", she does. Here`s another example....my husband and I do not have children and of course guess who suggests we should take family pictures and especially all the grandchildren (there are others in this family beside two brothers, but they just put up with this one person) should be with the grandparents(in-laws). Well...of course....we don`t have any kids and so...there will be no pictures of us. How convenient!! So.....please.....any advice would be greatly appreciated because now this "witch" is working in a place where she has access to my social security number and other personal info. And I`m afraid she`s going to do something. Thanks!
