Brian has a crush on a cute girl Sally from school so he goes and tells his dad about her and he says sorry son you cant like her she is your sister. So Brian is okay with it and he starts to like another girl Madison and he goes up to his dad and says I have a crush on this girl Madison and again the dad goes oh sorry son you cant like any girl in school they are all your sisters so he goes crying to his mom and says dad said I cant like any girl because they are all my sisters and the mom goes oh it's okay you can like any girl you want because he is not your dad.
