I think I've made it pretty clear in my other posts that I much preferred a dose of the slipper or, albeit to a lesser extent, the cane to "get it over with" rather than other drawn out punishments like lines or detention.
In my debate with Dr Dominum, I advanced a hypothetical scenario whereby a girl could walk roughshod over the rules with impunity and, for some reason which escapes me, seeing the "Near run thing (narrow escapes)" thread reminded me of an incident at school.
It was very rare for us to be given lines or detentions but, initially, there was some speculation as to what would happen if we just didn't do them. This ranged from "Nothing" (probability = 0 in my school but for a girl in some schools p = 1) to "One with the cane for every line not done (Wow! 500 of the best!) - knickers down an' all" (p > 0). I wasn't so sure about the last bit but even I would think twice before risking it.
It wasn't long before we discovered that the usual punishment for failing to do lines or detention was the slipper and about what we might have got for the offence we got the lines or detention for. I believe it was Prof.n who said the going rate at his school was two with the cane for missing a 3 hour Saturday detention. For us, detention was 30 minutes or an hour after school and our rate was 3 - 6 with the slipper. A very fair deal, in both cases, in my opinion
The incident I had in mind was when I was given lines (100 I think) to be done that evening, an evening when I was planning to go out. The obvious solution, of course, was to simply not do them and get the slipper the following day but, I don't know why, I just wanted to get it all over with so I said something like "Do I have to do them tonight?" To which the reply was along the lines of "Yes, if they're not done you'll get the slipper." No brainer really so I just said "OK, I may as well have it now". I was prepared for 3 or 4 fairly hard whacks but actually got off with a couple of fairly moderate ones.

In defiance of all the theories, if I had done those lines and missed going out I would probably still resent that teacher now. As it was, I gained even more respect for him because he didn't just let me off but he did seem to give credit (a milder slippering than I expected) for being honest and willing to accept a punishment.
I don't think that really counts as a narrow escape but I did escape both the punishment of lines and the potentially harsher punishment for not doing them.
Has anyone else here had a similar experience?
