Can someone suggest a Christmas gift for a stranger? Please read the details.

My daughter is bringing her boyfriend over on Christmas Eve for dinner. It will be our first time meeting him. I’ve asked her what should we get him and her reply has been, nothing. He will be staying for Christmas Eve and Christmas. He will not be with his family and I would feel horrible if we all opened something and he didn’t get at least a small token. She says not to worry because she has got him covered and he probably won’t have any money to buy us anything. (Which is fine with me.) She says dinner is enough.
He was suppose to fly home for xmas and my daughter was going to meet his folks but he insisted that he meet us first because it would be wrong to wisk her away without us meeting him first.
He is flying home from Europe and it has been a while since he has been with his family.
So I want to try to make the day cheery as possible.
So any ideas of a small sensible gift that he can carry easily as he travels?
