An ancient hobby

One of the favorite pass times....And the idea belongs to all of humanity. We have been doing it since the time we were primates.
With curly strands of hair caressing the ear, this little grandson of an Ice-cream vendor on the East Coast Road in Chennai, chewed that tiny little thumb of his, long even after my share of Cornetto was finished.
With stained hands of melted remains, i rushed to pull the camera out, not to miss the moment. But there was no necessity to hurry-up. The toddler was working on a long thumb-sucking session, with rhythmic repetitions. He did not know my intention and was quite content to hold himself still.
We have all done it. And some of us might have had a 'favorite finger' in this regard. He was one of us.
Perhaps his 'ice-cream' was unconditionally available and most important...... it never melted!
My clock had struck 2 pm.
