Strangers. Not around the house or your family. At the store, at the park, at work, at the gym, etc. People wish it to me all the time and I think it's nice and I appreciate the sentiment. I think it's very nice and it doesn't bother me. I don't wish it to other people because it feels rude and presumptuous. I don't really celebrate Christmas, and I don't assume that others do. How about you guys? Do you wish other people Merry Christmas if you don't really know them?
