Your father, much like yourself, grew up with a single parent in his life. Although it was his mother that was the one who he had instead of a father. This made two things in his life very apparent. The first thing, and the one he strives for you to continue, is his work ethic. Your grandmother had to be the one to get the family's money, and much like human society, women were paid much less than men on average, so your dad knew that he had to work hard in order to survive. The other thing that leads to his work ethic was that since he had nobody to fix things at home that broke, and his mother was always working two-to-three jobs, he had to be the one doing chores around the house after school and stuff.
The second thing that became apparent was that he had nobody to pass time with after his chores and homework was finished, so he got really into tv shows and cvs that were very fantasy-y, because they were an escape from the troubled reality that he lived in. He began to act more on that as he grew up, going to Game 'n geek parties at his friends' houses and spending a lot more time there rather than at home where conditions were really bad. You suspect this is why your dad never let your friends come over to your house for sleepovers, because he always did his sleepovers at other people's houses. Later, he got into cosplaying characters from comics that nobody read. This is how your dad and your momma met. Your momma was also a huge nerd, but she channeled her nerd energy towards social change, and so at one of the local comic-conventions, your momma and your dad both dressed up as characters in a comic that was so obscure, you couldn't even look it up with Oggle, and then they started rp-ing as those characters and then one thing led to another and then you were born, crystalizing that love your dad and momma had.
