In my experience girls are more emotional than guys. But not in every case! I'm personally not very emotional, but my brother is.... but us two are the only people I can think of who really go against the stereotype. If I said something to my group of friends who are male, I'd get a totally different reaction than I would from the females. And lots of my girl friends will bawl their eyes out at films, whereas you wont see a flicker from the boys. I'd say its the hormones that do it. Simple body chemistry.
Both sexes do get emotional from time to time but in my experience its the girls who do more and express it more dramatically or openly.
Everyone has emotions. Not just women.
And it doesn't come down to 'that time of the month'
It's about peoples feeling.. and everyone has them , no matter is your male or female.
If someone is really upset they will show there emotions, some try to be strong some don't. So i guess it's a question if you show them or not !
