about 30 years ago，i left cuba for the united states with my son．after getting settled finally in brunswick，new jersey，i enrolled(注册) my son in kindergarten．several weeks later，my son's teacher asked me to meet him at his office． in the teacher's office，an exchange of greetings was followed by his questions：“is your son mentally retarded(弱智的)? does he suffer from any kind of mental disability?”
