So many of these are just heartbreaking. 
Positive ones:
DH (then a fairly new BF) giving me a little lamb toy, telling me he one day wanted us to have a family, and that I was the person he wanted to be with, always. He'd also got me some cake.
My first longterm therapist in our very last session looking a little teary and telling me she was really going to miss me. I hadn't realised she might have any feelings about me really, despite seeing her for years. I was touched and happy (and cried quite a bit!).
Near the end of my last year in school, I was walking with my favourite teacher, feeling sad that the familiar was coming to an end and being a bit stroppy with the teacher. Instead of getting cross, she smiled at me and told me she was always going to remember me. I certainly still remember her so well!
Overhearing a different teacher tell DM: "Bursars will be fine, whatever she decides to do in life. She's got that something in her."
Not sure I want to write any negatives now. A lot of them are from my parents, like for many here. I've probably forgotten the worst ones, but these stay with me:
(I think I've said this here before). When I confided in DM about my cutting, her only comment was if needed help with the job or a sharper knife to finish it properly.
DF telling me he wouldn't come to my wedding if I married a black man.
DF when seeing me for the first time after I'd lost a lot of weight during a bad time with my bulimia: "You almost look like my daughter again."
Urgh.
