its a big secret cause some people are just to shy to talk about it. they think that none should know what is going on with your body. but sometimes you see how people are in big pain in class and you know its their period. it could really embarrass someone when they have to go to the nurse saying that it is because of their period, especially a man teacher!!=( Anyway, its embarrassing to say to someone about your period,especially young kids. it is way more embarrassing when you have blood going through your pants and EVERYONE sees it. taking about your period is like weird. it not like in a talk someone goes like "Hows your period" its a thing that people think it should be private.
