I will just add that we had the same experience with our son who didn't like to read when anyone was around except mom and dad. When he was 3.5 and in daycare, we would send him a note each day in his lunch bag. He announced one day that we should stop wasting our time with them because he wasn't reading them and that he was pretending that he didn't know how. When we pressed him on why he was pretending not to know how to read he simply told us that it was because the teachers would make a big deal out of it and he just wanted to be like all the other children, who could not read.
