These days we have some other visitors at our windows, apart from mynahs, sparrows, crows, the hateful pigeons and the disdainful parrot.

Their shouts are as cheerful and as incomprehensible.

They seem fearless, but our hearts pound as they cross our windows. Sometimes, they perch outside and ask for a glass of water. Sometimes, one of them answers his cell phone, or decides to switch on the music.

It’s when you watch them build the scaffolding as they climb up, or open it up as they end their work, that you realize fully what a feat it is to get the outside of a 30-storey building painted.
