Could it be that the MIL called my elderly parents and upset them by claiming I was strung out on crack? They flew way out West from Florida to see for themselves. Of course, I had to inform them of my vindictive MIL's demented brain. It turns out, her own son (the BIL) was strung out on cocaine, stole the family nest egg of $45K, and spent it like a teenager all within 18 months. She has never acknowledged this and is still in denial.
Sorry to hear that happened. Damn, that was a tough situation. I'm happy your folks were determined to see for themselves. I'm sure they rest much easier knowing the truth.
