What no spanker likes to hear

In my experience, no spanker has ever reacted kindly to my speaking up about bad aim

I have a tendency to mention how a swat was delivered either too high or too low. However, every time I do so, I encounter phrases such as "I know how to spank, young lady. I've been spanking longer than you have been alive." and "you think I have horrible aim?"Magically followed by a rampage of spanks delivered accurately to my sit pots, or "are you whining?" Sometimes I bite my tongue as single swat delivered amiss can be acceptable.  I must one day draw a perimeter around the acceptable spanking area. Never did I imagine being spanked would make me so finicky.
