Odd one out!

Why is it when you buy a tray of red geraniums, one is always pink?
Yesterday I got up at 3.15am to drive Charlotte and the children to Bordeaux. They caught the 7am flight to Gatwick where they spent a very unpleasant hour crammed in a very hot corridor waiting for passport control.
Meanwhile I came home and spent the day washing and doing housework.
Today, I did much of the same, while Mr F put up a new fence and prepared the hen house for some new residents.
We’ve been swimming in the afternoons, as by then the air temperature is 31 in the shade (which it still is now at 7pm) and the pool water temps are the same.  I need to go out now and do some watering but I can’t wait for it to cool down a bit.
