My father is closer than a grandfather. Your counter has no validity. He has had a big impact on my life and my interest in martial arts, which is most probably inherited.
Yes, which is why i also used uncle and Father as examples.......
Again, his impact on your life and interest, does not translate to you having his knowledge or ability, inherited or learned.
You are not him.
You are not amazing or knowledgable simply because he is.
That makes you sound about as arrogant and ignorant as they come
