One of my cousins is apparently a lot like me. I met him as a kid once. I stay far away from my mother’s side of the family so I don’t care to find some deep connection with him or anything. But he signed up for the marines shortly after I joined the army. We were briefly in Iraq together but never met. We both had alcohol problems, though mine was just health issues, while his was getting him in trouble with the law. Both got over it (not totally sober, but much healthier and safer and then pivoted “far” left as my mother says, and we both have gotten into smoking meats and gardening.

Genetics do play a role in our personality. Nature and Nurture components.

My daughters sense of humour and her smirk is exatcly like her grandfather’s and shes only seen him a few times in her life.

My son rubs his feet together as a self soothing / relax thing. His Grandfather used to do that in his arm chair. He died a decade before my son was born.
