Our next-door neighbour asked if he could borrow our tree lopper. Whilst he was busy, my wife happened to mention the shortage of flour at Tesco. The lopper was duly returned at the end of the job. That evening, neighbour went to Tesco to do their shopping. He rang us on his mobile, said he had a bag of flour in his hand, and would Mrs. bb like to have it? The flour was duly delivered by said neighbour, who would not accept payment, because we had lent him our tree lopper! Very good of him! But then, we probably saved him paying a tree surgeon £40 or so, by lending him the lopper. Tit for tat, you could say, but a nice gesture, nonetheless!
