I had been planning to

I had been planning to take Sunday 13th off, and spend it doing enjoyable things. Today, my brother booked himself a holiday in Cyprus, which means that he will not be able to work at the Parham House Garden Weekend that day, something he agreed to do almost six months ago. Nobody else can do it, as it involves driving a hired van – mum doesn’t drive and dad, being over 70, is not insured to drive it. Consequently, I’m going to have to give up my day off, and abandon my plans for that day.
To say that I am annoyed that he didn’t bother to check even his own diary before booking his holiday, thereby fouling up plans for the rest of the family, would be an extraordinarily polite understatement.
