I've always loved christmas lights with their soft, simple glow and the way they made me feel when I was back in our car in a puffy oversized coat squished between sleeping kids and all our new toys with my face close to the window where I can feel the cold just on the other side looking out at the streets all the warm houses each with their own christmas story but here I am in our car christmas songs playing softly in the background our parents talking quietly about the party but the parties are all over now and soon the decorations will be gone but next year you will take down your dusty boxes open the lids se thise christmas lights and all those car ride memories will come flooding back as that sense of confort and safety washes over you you will have answered your own question -why do you hang Christmas lights in your room?
