This thread is dedicated to all those little things that whilst not very annoying still bug you.
I'll start with:
1. People playing with your perfectly set toaster browning control that took days to set just right, then when the cornflakes run out you find all your toast blackened beyond recognition.
2. Buying a bottle of coke in anticipation for the weekend for addition to vodka for an evening in with the missus, then finding said bottle 3/4 gone in the living room with the top missing.
3. The local methodist church practicing their bellringing AT 9.30 AM EVERY SUNDAY!! Arrrrrrghh!
Your go.
