Yes, debcb, I would definitely be later than him. I have used this. It's hard as my H is home different times all the time. But, he always asks where I've been, and I usually respond with "I had some things to take care of."
It worked for me. Good luck. Just make sure you are being honest. Actually do something, or it will backfire on you. Others on this BB say it's because the H/W can see through the technique. I say it's karma. Don't lie, and you'll be fine.
