<human>: Condense the text into a few key points

My dad isn't usually the type of guy to help people for no reason but for some reason he decided to help this younger guy that got kicked out by his parents. My dad let him stay at his home, eat for free, helped him get a job, and even bailed him out of jail (for minor things) on 2 occassions. After about 6 months of this guy living with my dad, he finds out that he's sleeping with my mom. Apparently my mom had been doing meth with this kid and having sex with him just about the entire time. This kid was only 20 years old and having sex with my 45 year old mother in my dad's own bed! When I found this out I instantly stopped believing in karma. I was never really superstitious before but this did me in.
