When I came home for summer break after my freshman year of college I had to use my mom’s car to get around. Well my mom is the absolute worst person when it comes to auto maintenance. The 3rd day I was home and driving her car her engine blew a piston rod because the piston ceased in the cylinder. Turns out my mom never changed the oil. Like never ever. But because it happened while I was driving it was all my fault. I “must have been racing or doing something that caused the problem”. 25 years later she still thinks it was something I did.
