I don't give my T a holiday gift at this time of the year, but I've given her baked goods at other times. I know she likes them. I give her birthday presesnts, but they're mostly homemade cards. I've written her poems, too. I gave her a little stuffed kitten this year for a special time, and a stuffed bear to match mine.
My DBT T showed her "comfort kit" this week. In it, she has many cards given to her by clients. She said they're very meaningful to her, and almost teared up while looking at one of them. That made me realize that Ts DO have real feelings about us!
