Drawing on someone else's arm

Sometimes people decide to draw on other people's arms. This act of affection? can lead to hilarity or connection of dots (freckles) This simple act can be very strange. What is it about human nature that leads people to feel a need to graffiti other people. Some people might say that they do it because it is funny, others might just think that it is weird. How can drawing a kitty and a boat on the arm of their friend, express the deep-seated jealously of that person's skin and freckles. This act can even progress at far as highlighting veins. To most people this post must seem a tad bit random or odd, but trust me when I say that I speak from personal experience.
