Though this was quite funny...(It happened to me, so I'm allowed to say this) it didnt cause much of an embarassment for me, as I was asleep (of sorts)
I was cycling home from my girlfriends house when I felt a bit feint...I tried to pull over on my bicycle but it was too late...I blacked out, and essentially fell asleep on the path...only to wake up in the back of an ambulance, with a broekn down (in tears etc) mrs magical_trevor...she was glad to see I was now awake, but I had to ask...Is my bike ok...I got the look that tells you you're in trouble for asking instead of caring about the emotional state of your partener, but hey, its an expencive bike

Was mainly an embarassment due to the awkward journey to the hospital after the small but highly emotional conversation

EDIT:
Yep...my bad, didnt read that this had to be magic related, lmao...it kinda is, cos with a messed up bleeding face covered in cuts (as well as my hands) I couldnt do any magci for a few weeks
