Wickedness

The other day a friend told me things about her family. One of her sisters is married. She's always telling bad stuff about her husband. She's not happy about her husband, obviously. One day, she told everybody that her mother-in-law was really sick. Since this family come from Batak and the mother was quite old, and has got all her children married, the family knows that they would have to hold a big party (!) when the mother died (the father has long gone). The daughters and the daughter-in-laws would have to make identical black kebaya (to wear at the party) then.
So, this friend's sister told her family that her sister-in-laws said that all of them would have to make the kebaya in Medan (where the mother-in-law and some of her sister-in-laws live)! At first, my friend's family believed her. Because she stuck to her story. But after a while, it really didn't make any sense. My friend thought that it just couldn't be true. She suspected that her sister just made this up so that her husband's family looked foolish and ridiculous. Now, that was wicked! That was deceit.
My friend told me that she could stand mistakes or even stupidity. But wickedness? She's angry and sad at the same time that her sister could do such things.
