How to tell a male friend that he has his period skillfully?

? It seems that the subject is still a weak girl. As a girl, there seems to be nothing to say to her boyfriend for a few days every month. Boyfriends and boyfriends have become your actions, expressions or hobbies. If it's the first period you know, you can dangerously say "every month's miserable days are coming again", but any boy who is not a dull bird will know.

A few days ago, I saw a joke: my girlfriend sent a message to her boyfriend late at night saying, "Dear, my period is gone." Without saying anything, the boyfriend took a taxi to a nearby funeral shop and bought a big wreath to go to the menstrual home, saying that the boyfriend was stupid or a joke. When you meet a dull boy, he will occasionally point out others to avoid making unnecessary oolong.
