For me, it's peace and quiet.

Like IronRaven, sometimes there are giggles involved. The last time my wife's best friend practically jumped on my body and tried to climb up as high as she could when a little pig ran by behind her was very funny to me. She was practically on my shoulders after she grabbed my flashlight and saw it. The pig was only about the size of a medium to large dog. 75-100 pounds.

She never made it out of the tent again that night. It will be interesting to see how she behaves when we go camping this weekend.
