Thanks @lookingforward
My intention was to share my bemusement with my son-- who was amazed that he has to work until 6 pm on Christmas Eve. With teachers as parents, this is not a possibility that he had ever considered, that’s all.
Christmas is a holiday; Christmas Eve, while a big deal to some-- including my family- is not a holiday. I’m absolutely OK with him working in a supermarket until 6 pm on Christmas Eve. Not everyone has the luxury of today off to prepare for Christmas Eve.
