Just heard the best excuse ever for lying | ADHD Information

I've been asking DS (11) all week about a book report that's due Monday.  He's been telling me that he's been working on it at school, I've been asking him to bring it home so I can help proofread.

Tonight, of course, he does not have it.  He kept pretending to look for it, gave me three different locations that he knew he had put it.  I asked one last time where the paper was, since I had a sneaking suspicion that he knew and wasn't telling.  He then tells me that he completed it three weeks ago and turned it in early. 

I asked him, if that was the case why he had been telling me he'd been working on it at school this week.  His answer : "Because I thought you'd would think I was lying if I told you that." 

Sometimes I wish there really was a rewind button that would suck the words right back into their mouths, so you could remind them to think before they speak!  I also really wish that the schools would place more emphasis on reasoning skills, maybe then he'd be able to figure out that turning in an assignment early could be easily verified if I didn't believe him, while lying would definitely get him in trouble.  Not that I believe for a minute that he turned it in early.

  
This sounds exactly like that excuses my son gives.  I often hear 'I'm working on that at school, don't worry.'  Yeah right!  I don't believe anything about his school work anymore and make sure that I check his school diary every day and if not sure I write a note to his teachers.  I wonder if they ever grow out of this evasive lying?
