I stuffed myself full of food in the morning, which gave me stomach ache, and put me in a bad mood. Self induced. The cold wind was irritating, and blew my float fishing presentation out of the window. Two ducks hassled me for five hours solid, continually swimming around my float, making fishing impossible, and winding me up intensely.
I was so bored and sleepy when I finally did get a bite from a large carp, I didn't react quick enough and let it get into the snags.
Better luck next time hopefully.
