Read it through once

“I am happy to remark, my dear son, that you have resumed your former pleasures and seem to be returning to yourself. And yet you are still unhappy and still avoid our society. For some time I was lost in conjecture as to the cause of this, but yesterday an idea struck me, and if it is well founded, I conjure you to avow it. Reserve on such a point would be not only useless, but draw down treble misery on us all.”
