Summarize the following:
Whether you use your hands, a feather, or a brush, the best way to tickle a person is to use a light touch that causes a tingling sensation that makes people laugh. If you put in too much force, you'll just cause pain and won't be able to truly tickle the person. You can start with an extra light touch and tickle with a bit more force as the tickling ambush continues. This is a sensitive spot for many people, so you can try to delicately tickle this part of the feet first. Just remember that the softer the feet, the easier it is to tickle a person. If the person has rough or calloused feet, then they won't feel the pain here. Though this may be a hard place to reach if your victim is writhing and kicking, if you get under here, one of the most sensitive parts of a person's feet, then you'll be able to do some real damage. Try tickling the pad of the feet with one hand and tickling between the toes with another. Or try using one hand to hold the toes apart and tickling in between them with your other hand. This may be an unexpected place to tickle your victim — and all the better! This part of the feet is very sensitive to tickling as well. This is another very sensitive area of the feet and is perfect for being tickled, whether you're using your fingers, a feather, or a brush. Remember to use a light touch to heighten the tickling sensation and to avoid causing any pain to your victim. Though these are the most common places to tickle, every person has their own sensitive spots, and your victim may be sensitive in a different part of the foot. Keep experimenting and trying different parts of the foot, to see what makes your victim shriek the most. Here are some other places to try:  Just below the ankle  The top of the person's foot, where the toes start The sides of the person's feet The top of the foot  The middle of the sole Behind the heels Who says that you can tickle someone without getting it back? If you're out to tickle a person's feet, then chances are that the person will want to get you back. This may lead to a full-on tickle fight, where you're rolling around, trying to pin each other, and tickling each other's sides, feet, neck, and other sensitive areas of the body. If this happens to you, then you better reading up on tickle fights so you can make sure to come out the winner. If you think the person may come back and tickle you, then be prepared. Cover up your feet, or even your sides and neck, wearing as much clothing as you can. The person won't be able to tickle you if they can barely feel your body. But then again, if you want to have more fun, then ditch the tickle insurance and have at it!
