Here are two of the many snaps I got through email depicting Mumbai during the rains every year:
Paani paani re … car-mein paani .. sorry paani mein car re
Chaahe duniya doob rahi ho .. hum hain (saas-bahu) serial ke diwaane
Don’t know how authentic the second picture is but balcony mein khade bechare pati dev ki haalat pe zaroor gaur farmaana

Oh no, that doesn’t look pretty at all.
This was also the case in most low-lying parts of Bangalore last year.
Can’t imagine how people can survive such a deluge.
