Totally agree. I'll spare the details, however a long time ago a junior developer asked me to do a code review which happened to be on a critical part of the system which handles money -- not only was the code bad, it was incorrect as well. I decided to skip some meetings and I spend a few hours with him. We did a pair programming session, cleaned up the code and we discussed the merits of each approach while we were doing it. He didn't say anything at the time, however I found a blog post from him a few years later where he described the experience as invaluable and a driver to help him to try and improve his craft.
