I just simply brush it off, buy not going out The House, not turning on the TV, and not involving myself in way I could gain some information of what is happening outside. I might feel that something is different, but at least it wouldn't be brushed onto my face that it's holiday related to something. For me, rather it's just a day to relax and withdraw myself from the world, be a hermit.
Your question is a bit odd, because you can easily and simply just not participate in whatever gathering the holiday entails, like Christmas for example. You can just lock yourself up in your room and not go outside like you said, unless you are being forced to by your parents, relatives, or friends.
I agree. The only sure-fire way to avoid everything or anything is to lock yourself in your room, switch off your phone, avoid getting on the net and watch movies all day long or for as long as the holiday season lasts.
