I would jump over an elephant for a Nice biscuit. Well, not really. I couldn't. I'm in my sixties and would just crash into the poor animal who would probably trample me for my troubles. She wouldn't have a clue what I was after.
In olden days,
Nice biscuits were a thing. I don't do sweets now and have no idea whether these treats are even available anymore. But if they are, do me the kindness of buying a package of them and passing on the humanitarian gesture that goes along with them, Give them to someone you don't know.
All they need to do is smile, and all you need to say is, "Thank you for smiling." This is the idealism I evolved to seek, and found. Now it's pay it forward time.
