A salutary lesson for me

I was returning an item to a department store in Bromley. The assistant asked me to go with him to the section where the goods were sold to check on the barcode number. As we were walking across the store a lady came up to the assistant and said that she was the man she needed and proceeded to open her shopping bag to retrieve something. I was just about to remonstrate with her saying he was doing something for me when she handed him a package and apologised for not giving it to him before Christmas. It was a Christmas present and she then told me how helpful he had been throughout the year and she wanted to give him a little something.
I am so glad that she found the present before I had a chance to say anything. Somewhere in this is a lesson for us all, well me at least, and perhaps the beginning of a New Year resolution.
