One Wrong Move Is All It Takes

I did something really stupid tonight, it only took one drop of water but it was enough to really cause an arse ache.

Moving a pan of oil from the cooker to the worktop, I passed the sink and caught the tap causing water to drip in. The oil bubbled up and sprayed the newly painted wall and my arm. *sigh*

Is there any other type of frustration that is worse that one with yourself?
