>>48945856Ash's father abandoned him when he was a toodler and his mothers only wanted him to turn 10 to leave the house and she return to her single life (It's canon, read the novel), both of Misty's parents abandoned her when she was a baby in the care of her tween sister, Brock's parents abandoned him so that he could alone raise his little brothers and sisters.
Believe me kids in Pokemonworld are better without that kind of parent, at least Ash was adopted by a better family.
