Gaining family members is one of the great things about getting married but sometimes, sibling-in-laws can be a bit of a headache.
Maybe you found out your sister-in-law tried to reunite your spouse with their ex behind your back.
Perhaps your brother-in-law forged your signature on a parental consent form so that your child could get piercings.
Or maybe your sister-in-law wore a long, white dress to your wedding in an attempt to upstage you, the bride.
Or perhaps your sibling-in-law was house-sitting for you and burned down a wall in your house from playing with fireworks in your backyard.
