Comparing between what I see and What I am doing.
Near Nehru Place, marks left by the gardener on Day 1 and 2 days later, the marks have changed in appearance. But the Marks I have left on the wall, the traces of what I have been thinking are of permanent nature.
In my case I use a pen to draw a permanent line which can be white washed, painted over. But in the case of the Gardener, it is changing by the minute and over a period of a 24 hour cycle, it has changed form.
