Just got another parcel from America. A book from a second-hand book shop. This time the envelope had been slashed open across the name and address. It had been stuck back together so that the name was completely obscured and the only part left of the address was the post code. Somehow it found its way to me because the local post office staff know about my American connections and they made a clever guess.
Hooray for old-fashioned rural service. Cheers, Joy
