It's a dangerous sport, fishing, Max. I've had a few hooks in my hands (nothing like yours, though), back of the ears, etc in my time.
My clearest fishing memory which involved pain (actually, more fear than anything) was when I went down to the Castle Douglas loch by myself to fish (usually went with a friend). I would have been about 9 and all we'd ever caught up till then were tiny wee perch. There were pike in the loch, though, and this was to be the day that one of them decided to attach himself to my hook. Initially elated, I started to reel him in, but as he got closer and I saw what a huge evil looking monster he was (if you've ever seen a pike's mouth close up, you'll know what I mean), I was torn between being able to boast to my friends and family with the proof in hand and the sheer terror of sticking my hand in its mouth to get the hook out, even if I had managed to knock him on the head, which would have been doubtful, given his size. As he got closer and closer, I was seriously contemplating cutting the line, he looked so menacing. I was just about to step in and lift the line out, when (luckily for me) he put up one last major struggle and got free. Phew! The one that got away and I was quite happy about it!
