I did my bit.

Yes I did.  It would have been rude of me not to. Went out and
 bought a packet of sparklers in order to contribute to the air pollution
levels last night. Got a lungful of sparkler smoke in the bargain.

 Okay, I confess. The real reason I bought those sparklers was
for that smile you see in the picture above. My mom's housekeeper couldn't
go home for this Diwali, so we didn't want her to miss out. She lit candles
at my mom's front door, and had a great time playing with the sparklers.
The cough I have this morning was totally worth it.
