One of the senior professors from my department is retiring. This time I want to give something individual rather than participate in a group gift, and am wondering what would be a good gift. Any ideas or advice will be much appreciated.
My advice would be to find out what the colleague plans to do in retirement. If they are selling everything to move across the country, a very small or non-tangible gift like a gift card might be preferable. A travel gadget if they plan to take a long trip. If they are planning to work on their garden, something related to that. Etc.
