The norm says
Boys will be boys, especially the ones we love. It teaches us to let their poor behaviours slide, to accept them even, and not to take them too seriously because "they don't really mean any harm".
Will remind you not to let internalised patriarchy settle in. Set positive precedents for yourself and other women by loving the boys and men in your life so much so that you speak up when they are wrong.
Or, it will just empower the heck out of you. Hopefully both.
