I don't Understand Farmers

For the life of me I don't understand the way farmers think. Last weekend it rained over 2 inches, which means that no one did any field work all week long. So you think that they would have time to plan out what they want to do when the fields are fit again. Well yesterday was the perfect example of how they don't plan anything at all. A farmer walks in yesterday at 10:30 in the morning saying that he wanted to put in the corn plot for one of my locations, and he wanted to do it at 1:30 that afternoon. Well I wasn't even working yesterday and had to canel all my plans for that day because this farmer decided that he wanted to plant. For the life of me I can't understand how that came to be a last minute decision.
