Well, yes, but a shallow skin graze is not major surgery (or even minor!). My point is that we are getting excessively frightened of... well... life!
The couple in the story have had a life adventure which has not harmed them in any way. They don't need compensation.
So licking a graze clean, if your tongue can reach it (challenging on one's own forehead) is not such a daft idea
. Could have spat on my hanky, I suppose. Actually, if The First Aider Designate had not pounced on me (something to do, something to do!
), that's probably what I would have done, or just given it a dab with my hanky. And it would have been just fine. After all, I've survived such treatment so far.
