Do girls feel particularly wronged starting from the age of 13, having to spend a few more yuan each month on sanitary napkins (of course, this applies to physiologically normal female friends), and therefore hold out for their boyfriends (husbands) to spend money on them? In fact, men's money doesn't grow on trees either...
I'm thinking, why do female friends live longer on average than male friends, aside from women generally not smoking or drinking as much? There's another main reason: men bear heavier social responsibilities and have to endure much more life pressure than women.
If you're a girl, you can make a fuss over anything that comes to mind, cry when you're upset, laugh when you're happy, be coquettish and willful, and express your feelings in all sorts of ways until you feel better. No one will say anything... Girls are allowed to be emotional, everyone can forgive your mood swings. You can commit occasional acts of intermittent madness without considering the consequences, and then justify it by saying: "We all have those days every month... I didn't mean to..."
Think about it, isn't it true that every time you coquettishly tell him this, he always wraps his arms around you and says, "You're still cute even when you're throwing a tantrum!" This old trick never fails, even if you kick their ten-year-old cat to death during one of your episodes. Who would want to argue with you?
