I am a current MS4 and I have decided what specialty I am planning on matching into. When I was on that rotation last year, my chief resident was a really great teacher that I really enjoyed working with and is one of the people that encouraged me to choose this specialty. He has since graduated and moved away, so I haven't spoken to him in a while. Is it considered weird to send him an email or a text to let him know that I have picked this specialty and that his teaching had a big impact on me? Would a resident appreciate hearing this or would they likely not even remember me and find it odd to hear from me out of the blue like this?
