I used to babysit my friend's two daughters (ages 5 and 7). The little girls had seen my bare feet countless times, as we always went barefoot together, but after a period of time, they got into the habit of tickling them every time they saw them, sometimes to the point of torture. In fact, the 5-year-old could make me laugh so hard that I couldn't breathe for a long time. Those little girls were as cute as cute can be, but, oh, so brutal when it came to tickling my bare feet. The strange thing is, the longer and harder those little princesses tickled my feet, the more love I felt for them. (I'm talking affection; NOT erotica!) They apparently felt the same way, because after every foot tickling, I would get a kiss and a hug. It tickled like the dickens, but it was well worth it!
