Learned by sitting next to you

“Almost everything I know about doing this job well, I learned by sitting near you and paying attention, which is not a training programme anybody designed. You explained things without ever making me feel slow for asking, and you did it while carrying your own workload. Thank you. I have tried to do the same for the newer people.”

Best for: Long thank you message to a colleague who taught you informally.
