Instead of paying his contractor's insurance ($400), he took the money to buy a flatscreen tv.
His wife refused to work, and spent grocery money on waxing her "personal regions" and getting her nails done.
They let their car insurance and registration lapse.
Their child went without even the CHIP insurance.
It was not until we completely cut them off, let them get evicted, etc., that they actually started doing things for themselves -- complaining bitterly the whole time about the unfairness of it all, because they "needed" the help.
You all did your level best, and your brother and SIL blew it. A flatscreen TV? Waxing and nails? Sheesh...
