For once, the title should tell you what this week’s crib is about. The Metro train, or for that matter any public transport, may rightly be the lifeline of a city, but is also a portable museum of the ­crankiest characters you’ll ever find. ‘Aap ek Chaddha ji ke baare mein likhte rehte ho. You will find 10 different kinds of Chaddha jis in the metro,’ said the intern, Anurvi, in my team. She went on to list some.Neha, Aditi, Medha, Debasmita, Khyati — just some of my colleagues who are regular travellers on the metro, were too quick to point out the various kinds of weirdos they encounter daily. Excitedly enough, I went around looking for them myself, and realised that such people might be irritants if you have to bear with their antics at the end of a hard, exhausting day, but are also quite the answer if you are looking for some good, free amusement.
