here’s a little test for all you parents out there (and I’m sure plenty of non-parents will figure this out too)

If a kid’s nose bleeds a little trickle, then promptly stops so you send him on his merry way then he comes back complaining of nose bleed again, which promptly stops again then the whole thing happens again….

What is causing the nosebleed?

…the school nurse didn’t know this. But she learned it today.
