Sailor's trousers

My gran would always say that the washing was safe on the line "If there were enough blue in the sky to make a sailor a pair of trousers". The sun's still shining but we're getting twitchy here. I seem to have spent the whole week fretting about the weather. Still if that's all I've got to worry about then life must be good. It's not as though we're expecting a hurricane. Are we Mr fish ....?
