Certain misdeeds chase me like demons of doom: most of the time I get punished for things I had already done wrong before, and suffered the consequences for, possibly several times.
It would be tempting to say: "Well, obviously, spanking doesn't work if you re-offend," but it's not so simple.
I don't react well to being expected to reform once and for all after only one occasion. Whether there's a spanking involved or not, the "go forth and sin no more, EVER" approach only makes me resentful: if I *could* avoid certain undesirable behaviour for the rest of my life, then I would, punishment or no punishment. I expect to live for a long time, though, and I don't anticipate spending any part of my life as a saint - which would certainly be the implication if all my usual quirks and badnesses were corrected forever within the next few years.*
One of my pet hates is hearing the phrase "Obviously, last time I didn't punish you hard enough." I don't hate it in a love/hate way: it just irritates the hell out of me. I'm not receptive to punishment when I'm irritated.
On the other hand, the phrase "I let you off last time", said in a hurt, regretful tone shred me into tiny little pieces.
