My dad grew up in a very traditional conservative Spanish household, all very catholic (though he was always agnostic) and stuff, he was the seventh son, but he wasn’t even the youngest so he didn’t get much attention. He also had OCD and social anxiety (not being able to be in a train or elevator with many people,etc). He also travelled a lot for work when I was young. So growing up he was very critical of me, I was very ADHD and hyper, always constantly doing annoying shit and agitating things, so he would loose his patience a lot. When I got to the extremes, yelling for long periods of time, etc, he would slap me, or leave outside the house for hours, or throw whatever I had in my hand at the moment out the window. The kinds of stuff his dad would do (his dad was born in 1923 North Spain so those things were common) to get me to stop. This was until my brother was born, from that point on he did a complete 180; got super calm, became a lot more patient, he stopped traveling so much for work (though that may have had more to do with that fact that there was less work in general cause this was around 08) he would yell a whole lot less (like only when we really got crazy) and I have never seen him strike my brother in his life. I don’t know what happened but something changed. I’ve always loved my dad, and I really admire him as a role model because he’s an outstanding person and an extremely intelligent man (except for social skills). I just don’t know how what took him to change his parenting strategy, anyways I’m glad it did.
