Even though I often didn't see my father for months at a time, I know he loved me as much as I love you, Son, and as he once said to me, 'I may not be the best father, but I will always send my prayers when you need them the most,' and that is what I intend to do for you. Remember this, even if you don't see me for a while and want to hate me, I love you.
A culture must hide its hands in the arm of their clothing as a sign of respect and peace. When approaching somebody you show them respect by crossing your arms and hiding the hands in the shirt sleeves. Nobody worries about hidden knives and such, it is the threat of magic that this custom was created to prevent.
