in your critique. You gave constructive feedback that was easier to
hear coming from you than from a professor or another student."
"International students will profit from your kindness and understanding."
"You don't confine yourself to what's on paper, you probe and ask about the thinking behind it."

the encouragement to do them."
"You took an interest in my
field, but as you are a layperson, it forced me to write clearly and
not skip things or assume any steps in my reasoning. You could analyze
my advisor's writing style too, and you helped me write more like him so
he would like it."
"It was great to get your feedback after the project was done, comparing the final draft to the first draft."
"You see me as a writer, as a professional who will be published in my field, so I had better be a good writer as well as a good scientist. You care about my career."
"You don't waver in your explaining [of English idioms and grammar]. You say 'Here are three ways to say this' and explain [the shades of meaning that] each will convey, and let me choose."

"Whoa, you know EVERYTHING!" [a high school student, during an explanation of various literary and historical allusions]
"I received great feedback from my instructors on the papers I submitted. Thank you for all your help."
