During my worst depression ever, a friend said to me "I like you. Even if you are sad...".
It made me feel better because he didn't try to cheer me up or make me feel like I had to be okay. He enjoyed talking to me, fuucked up mood and all.

Recently a coworker said to me "you have an answer for everything!" when I came up with an example to answer a student's question. I thought she was being sarcastic but she was actually being sincere, and said she can always count on me to come up with an answer or example to clarify a student's misconceptions at a moments notice. That was nice to hear.
