Dear Abby:

Iím almost sure my wife is cheating on me. On her ladiesí night out she has been getting home later and later. Someone drops her off at the corner and she walks to the house. The last time, I hid behind my Harley in the driveway to see if I could determine who is dropping her off. While crouching behind the bike, I noticed a puddle of oil on the driveway. Should I try to fix it myself or should I take it to the dealer?
