Avoid having sisters at all costs.

My older, unmarried sister is jealous that my younger sister is getting married. If I have to hear from her one more word about what my mother is spending on the wedding I am going to scream. She seems to think that it isn't fair that my mother is paying for the wedding and my sister is in debt because of the stupid things she buys, and then can't pay her electric bill, and my mother won't give her the same amount of money.

Duh, Sue, it's a wedding. Totally different from mom paying your bills because you spend frivolously. Besides, it isn't like she hasn't helped you out plenty of times.

God, my family is so fucked up. We define dysfunctional.
