When I used to play along the banks, of lakes, rivers, and streams, I would pick up the pebbles, and feel them. They were smoothed out from the water flowing over them for years, smoothing them down, shaping them. They were always very pretty, and each was unique. I always felt nice and relaxed holding onto them.
Some people in your life are like the pebble, in a way. Its like the river is life, racing past, rushing all around you, but they are just as smooth and as beautiful as can be, letting life shape them, but not dragging them down, or shuffling them around. They still move at their own pace, but like a pebble, they are unique and when you hold them close to you, it makes you feel warm and at peace, and no matter how hectic life gets they are there to remind you of what is important.
