Jim. I agree with Joe. I sounds like you handled that one pretty well - just
be careful not to overplay your hand. It's tricky walking such a fine line.
In future, you may have to throw in a little "but gee Honey, I was going to
get started on building you that new blurfl tonight". The key is making it
sound natural. Practice that a couple of times a day, and you should have it
down in no time.
Good on you for dodging that one, and happy woodworking.
