Swimming Laps

I shouldn't use the word laps because it's a small pool but how else can I keep track. The first day I did about 10 because I lost count. The next morning I collected 15 pebbles and at every lap I shifted a stone to a new pile. I did 15 laps. Today I threw away 5 pebbles and shifted the stones into one pile and then back. So I did 20. Tomorrow I will try for 30. I not sure you can qualify what I am doing as swimming. I lie on my back and relax and kick and either flutter my hands by my sides or do a big sweeping stroke. These mornings I surrender to floating - the water holding me - and the sky - with the overhanging trees and clouds. Sometimes life is good!
