I felt a bit patronised and uncomfortable at the time, and briefly thought he was being sarcastic. I noticed that sometimes after I had finished explaining stuff, he would issue unsolicited compliments, in an obvious attempt to make me feel good about myself, and to be truthful; it just felt phony and contrived. But in retrospect, he was probably just working in line with his professional training, and didn't mean to come across as sarcastic, phony, or contrived. They were just my perceptions, and not necessarily an accurate perception of intent.
