Props to this person for never washing their mouth off their friend’s blood. I’m sure they had the chance to do it, but chose to walk all over the hospital with their mouth covered in blood so that the nurse could see it, otherwise the joke wouldn’t have landed.
I don’t know how hospitals work in the US (assuming that OP is a US citizen, because that’s what we do on the internet), but where I come from, determining the cause of an injury is very important to decide on an effective treatment. Bites in particular are very nasty and can lead to a lot of scary complications (including human bites!).
There’s no way in hell the nurse just said “yeah ok got it fam” and went along with her day like it wasn’t important.
And maybe I’m too jaded, but I read “we also got engaged” and my mind automatically added “and everyone clapped” at the end of the sentence lol
