Muduh, 6 months after my dad retired, my mom went back to work!
He needs a hobby. One that only he can do. Like fishing or something. Habitat is a GREAT idea for him. They are such a great project and they need people with skills. My husband has always said that when he retires, he's going to go volunteer for Habitat. Maybe your involvement with habitat could be to make cookies for the workers once a week or so and send them with your hubby when he volunteers.
I'd flat out tell him. "I'm so happy you are going to be home and I look forward to having time together, but we also need time apart or our time together isn't going to be as much fun if we are together too much. YOu need friends and hobbies and I need friends and hobbies so that when we are together, we have something else to talk about other than how much you are getting on my last nerve!!!!" (sorry, you don't have to add that last part )
Should we change our screen names? Oh wait, Lucy is already taken on here.
I know exactly what you mean about the candy factory. LOVED that show so much.
