Well I don’t really know the daily life there in real life but in here Neither children nor the parents says “I love you” before leaving. They may say Becareful, or don’t forget this or that or come back straight to home but never ever I have seen any family to say “I love you” before leaving for school or work. It’s just never happens.
In movies powers are often overestimated or underestimated. In a typical action movies like Undisputed, they get like a kick on the head or on the neck amd act like It’s nothing wien a hit anywhere near the head or neck will leave you dizzy the rest of the time in the fight. They punch in the face like you one, then I one when a punch on the face usually is extremely painful, it can even turn you unconscious.
