"What do you want for Christmas?". All I want is peace & quiet. There are no "gifts" I wish for.
.....And the more you push me for suggestions, saying "But you have to have something!", the grumpier I'm likely to become. Is it that difficult to understand? I have everything I want, there is nothing I need. Why do you feel I have to have something? Does buying stuff for people make you feel good?
You don't have to buy me anything. I'm really not being ungrateful, I just don't want you wasting your hard-earned on something that will either go in the bin, or to charity, after New Year.
