<p>I think you should print out the letter – and not mail it. </p>
<p>I sympathize with your anger and need to vent, but I don’t think the letter will do anything for your son except possibly expose him to embarrassment that his parent is stepping in to vent to Harvard over a situation that directly affects your son, who is a grown man.</p>
<p>I think that the best thing that you can do now is to help yourself and your son move on to take advantage of whatever college options he has. Your spending time and effort venting to Harvard isn’t helping with this.</p>
