If you have a regular girl, don't see her at the same time or the same day every time. Vary the routine to throw the wife off the trail.

Don't have anything written down, either on paper or on a computer. You could put her phone number in an electronic organizer that's protected with a secret function. I suppose the FBI or CIA could crack one of those gadgets if they thought you were a terrorist. But chances are, your wife won't be able to.

Use cash for everything, including any transportation. Don't have any credit card charges from strange hotels, or even gasoline in a strange city.

Where to get cash might be a problem for some guys, though. If you do the household finances, it'll be easier than if you don't. You can be an Enron exec and skim it off the top. LOL.

If the girl uses perfume, buy gas on the way home and find a way to spill it on yourself. The odor of gas will overcome just about anything.

And the one I've been harping on: Don't use a cell phone. Buy a disposable phone card from 7-11 and use it from a regular phone.

1)Don't use your computer at home; 2)Don't use your cell phone to call us; 3)Don't use your credit cards to book us; 4)Don't meet us in public especially if you're married; 5)Don't fall in love with us; and 6)Don't negotiate our rates

1) Do write us very nice reviews 2)Do re-schedule another date before leaving; 3)Do bring us gifts; 4)Do have good hygene; 5)Do remember our birthdays; and 6)Do take us on a nice vacation at least once a year!

DON'T DO IT!

The only thing you have to do is know your wife, yes no credit cards, no hotel bills, unless you travel all the time...your cell phone will not have the number on the bill unless it is long distance and most ladies don't answer their phone if it is a blocked number ! We like to know who we are dealing with.  Computer girl has it all right....most professional prefered clients do all the nice things she has mentioned...the mistress loves to be spoiled and will reward so much happier in return!  Good luck and don't deprive yourself!!

Easiest way is don't. that aside

Don't do anything from home
no souveneirs
cash when possible not from household accounts
Hobby out of town if you can
Limit paper record as best you can
Get some program you trust to clean your computer record.  otherwise you are looking at making the hard drive disappear in an emergency.

My cell phone bill (Sprint) lists every out going number local or long distance so if you use your phone have the bill paid at the office.

If you can't lie to your wife and have her believe it, don't put yourself in a position where you will need to.

good luck

Other Don'ts:
Don't change your attitute around the house.  If you are miserable before hobbying, stay miserable after hobbying.  Women are keenly aware of emotions and their changes

Don't start creating new needs to be out of the house.  A new hobby such as this should not interfere in your normal family routine.

Don't bring in newly learned techniques into the bedroom (even if you sporadically have sex).  Bringing in new techniques are okay if you are able to discuss things as in "Honey, what do you think about doing X?"
