Perhaps he doesn't think being held for 30-60 minutes is fine. At least he now feels comfortable enough to tell you the truth.
There was a guy that used to frequent these forums (years ago), and he used to say (something to the effect), Are your monitors your friends? Would you treat your friends like that?
My advice is to learn to appreciate what your monitor is, and stop trying to make it into something it isn't. This does not mean a monitor can't be tame and/or like interacting with you, it means it should be on their terms and acceptance not yours or mine.
Good Luck,
