It's a bad week, yes, but we've had this poo before and got through. For me, the worst thing is facing that mountain of work when we get back when the weather settles. It's a bit boring sitting around, so get some 1000 piece jigsaws of Windsor Palace in to amuse yourself.
Going to hammer here later on, and the custards know it. Even if you don't pee them off today, they won't forget that you did them in the rain and won't be happy with you and are then more likely to dump you in the future.
