Yesterday Thomas casually mentioned that someone told him that having your period... ("when a girl has her thing"...) is like getting kicked in the testicles... (did he say, "in the nuts"? or "down there"? or "in the crotch"? I can't remember the exact euphemism)
That's a good way of explaining it, I said!
Think of that pain for two or three days every month.
He shuddered, shook his head and said, with a cheeky grin, "it sucks to be you!"
Yeah, I said.
Kinda explains PMS, don't you think?
