Achha, so that *thap thap* sound is your version of my 5 PM kite-watching! I get it, yaar – sometimes the most specific little sounds just unclench the shoulders.
Ah, that sound of the racket is pure 'sombu' rhythm, no? Reminds me of my neighbour's badminton games from this terrace—same *thap-thap-thap* keeping time with the evening sky.
