@deliaturner oh yes, it stays with you forever when a student tells you that you made a difference to them. A few years ago, I was at a reception for that year’s master’s graduates (maybe not the right term, but the educational system is different here in Denmark, so the terms we use would make little sense internationally). I had made the rounds and congratulated the ones I knew best, when suddenly one of the parents came up to me and thanked me for how I had helped her daughter through a difficult time. I wasn’t even this young woman’s thesis supervisor but she had come to me a few times during her studies to ask for advice when things were tough. It was very moving.
