He was a substance abuser. My mom just put me and my sister in my grandma's car and told her to take us to her place while my mom went to work and stayed at her friend's house :p He drove around drunk with my older sister in the back sitting on his pack of beers when she was like 4. She never had to be the designated driver for him because he decided to keep driving even while drunk, however he did ask her to pass him a beer from the pack- ANYWAYS that dug a bit into my trauma too much, sorry about that, have a nice day!
