myfriend: Why wouldn’t you tell someone to enjoy their holiday. People whom I come in contact with who know that I am Jewish always wish me a good holiday. I always tell people to enjoy their holiday and wish them and their family good health and happiness for the coming year. In addition, I give something to my hairdresser and the lady who does my nails. My neighbors have been extremely kind to me since I moved into this building. I have had surgery several times and they check up on me and have done some grocery shopping for me. I often give them a little something at this time of the year. Usually it is just some baking and I try to give it to them closer to their holiday when they have more company and could use it. There is certainly nothing wrong with showing appreciation to people at ANY time of the year. It just seems that it has become a North American tradition to do it in December. It also seems that no matter how many times you explain to non-Jews, they believe that Chanukah is the Jewish Xmas because of the time of year and the gifts. It is also now not unusual to see Chanukah decorations and supplies in the stores right alongside the Xmas things. Therefore, if they expect something from you, it would naturally be expected now.
Anyway, good wishes to another, even if not sincere, are just plain good manners.
