Depends on what you got
If I gave someone a gift I wouldn't expect one in return.
Is this person the opposite gender? 🤔
If it's a gift just for you, and it is in some way personalized to you (so not just like some baked goods or a gift card), I would reciprocate to show the person I appreciated the thought, but I wouldn't feel any pressure to do so right away. A sincere thank you or a nice handwritten card are enough for the season, especially if you are not giving out gifts to others at work.
yea, do it. I regret not doing so.
