My dear, dear, sweet family which excludes women save myself,
Peeing standing up is your birthright. Urinating standing up (or squatting, kneeling or lying down for that matter) in the middle of playgrounds, parking lots, grocery stores, or any otherwise public arena is not acceptable. This goes for all of you, including the big one. Nathan-- your peeing standing up IS cute and your heart is in the right place but please, lets wait until you are tall enough to pee INTO the bowl instead of urinating all over the side of it, ok?
Your loving mother
