I don't give holiday gifts because she takes off the last two weeks of December each year...avoids the question and I like it that way. But I do give her what I call a "theraversary present" on the anniversary of our first meeting. Last year it was a gift certificate to a cupcake bakery and for next year a creative toy for her office. She does not give me gifts and I am careful about the monetary value not being too high so that it doesn't create an ethical conflict for her. I like doing something to commemorate the occasion because it is meaningful to me.
