If your lover or fling has a pet you need to be cautious of the hair and smells you might be bringing home with you as well.  Coming home with dog or cat hair all over your jacket or pants all the time and you don’t have pets or a different color pet, this could lead to suspicious and lead you to get caught.  Always carry a lint or hair roller with you that way any extra hair that you might have picked up while having your date doesn’t come home with you.  Make sure you dispose of the used sticky paper before you get home as well that way nothing is left to question. Make sure you brush yourself with it before entering your car as well.  This way there is no transfer of hair to your vehicle.  This can also cut down on any hair from your partner that might be on your clothes or car.  Its better to be safe than sorry.
