My oldest son is on the spectrum and there are times when sarcasm, vagaries, pronouns, and, well, Tuesdays throw him for a loop. As fluent as I am in his language I can usually tell where he's going with something, but since he's now a teen it is increasingly important he learn to express himself clearly and independently. Therefore, I no longer "let him off the hook", but instead ask questions to try and get him to more fully engage. And there are times, Lord help us, there are times, when I hear our conversation and the best way to describe it is that timeless Abbott and Costello search for truth. I have faith that eventually, my son will find his answers.
