Some people tend to unlike snow days because it seems to be uncomfortable for them to go somewhere. On the other hand, snow days will also give you the chance to stay home and do a proper organization of the things in the house. This could be a good time for you to inspect and fix the problems of the smoke alarm. Furthermore, you can try to clean or arrange drawers and cabinets in the house. I think snow days can be worthwhile if you know how you can improve your house while you stay there.
