As a matter of fact, we will be "celebrating" "chrismukkah" soon (see wiki definition). The truth is that I don't really know what it is ! We end up with a light mix of secular gestures and references: plenty of light and colorful decorations. That's what it is, I guess.
What's paramount is that it remains a great time for children.
As for me, on the very day, I can't escape from a moment of gloomy spirit. I heard I am not the only one...
