Try not to sit on chilly ground

So two or three weeks prior, me and my companions were perched on this bond sort of platform (as we called it) It's essentially the means up to the versatile. (classroom that nobody uses) and this irregular supply French instructor comes up to us and says: you shouldn't sit on this ground, it's excessively cool and it's terrible for your ovaries. I asked her how or for what good reason and she said that if youngsters sit on cool ground their ovaries will solidify and that we won't have the capacity to have children. Presently it's an inside joke between us about not sitting on cool ground.
