It will go faster than you think. But then there are all the good eats you must do something with.
Welcome to the KK life. It's rough sitting around sniffing the smell from that new cooker. (It can go on for 18-20 hours or more.)
Takes a lot of effort to not pop that lid, but a couple of cool ones on the side should settle you right down.
You will find your habits changing. No, longer will the wife prepare the meat and bring it out to you at the grill. That will no longer be tolerated as to you will not let anyone else prepare and apply your special rubs etc.
The initial shock will be hard on the little lady, so go easy. Be nice and let her wash your tongs when you have finished. She just might carry you a few beverages. (and a fine cigar)
Yes... it's going to get rough.. handle handle handle it. If not may be the wife can do that to.
