^kissing and hugging a 30 years old son is not necessary.
But your wife can kiss you? Not your mother who had you in her womb and gave life to you, raised you up and was there when you needed her most? And the father who secured your life by giving you a roof over your head and a good education so you one day become a succesful man.
But your wife has that right!
Come again when your kids have become 30 and tell me you don't hug 'em and kiss 'em...See you then!
