One of the main issues I can think of at the moment, about giving my T a holiday gift, would be my strong attachment towards her, and that's probably why I want to give her something I believe she would enjoy (a baked good or sth).

But I'm also afraid of her declining it, saying she cannot accept it due to safety concerns, or something else. That would be terrible.

I was initially thinking, if I decided towards giving her the holiday gift, that I wanted it to be a surprise, but now I'm thinking it's best to talk to her in advance if I make up my mind. I still have 3 weeks before I go on my holiday break, and I won't see her til mid January (it's almost Summer here, and she's going to take the first couple weeks of the new year off.) so I still have some time to think this through.
