Once my dad left I had no contact with the grandparents on his side. They are probably both dead by now. One of my aunts said they used to kick my dad's ass on a regular basis when he was growing up, so no great loss.

Had no contact with my mom's dad since he was disowned when he started molesting my mother. My mom's mom was evil, her emotional cruelty was far worse than the beatings my mom used to hand out. I take great comfort in knowing that "Nana" smoked herself into an early grave after a long, painful, withering bout of lung disease.
