That brand is not available anymore!

Few months ago I was traveling in a crowded bus. Usually I prefer reading or chatting on the phone while traveling. But, as the bus was too crowded, I was left with no other option than to stand for next half an hour.
There were few advertisements placed on the bus panel. I started skimming over until one of them caught my attention. It was a few months old ad for Kala Ghoda Poetry and literature festival. It had a short Marathi poetry (charoli) by one of the contemporary poets. It was about two friends strolling in the park. One says “These days I don’t see those tiny yellow butterflies around” Another replies “Sorry buddy, but, that brand is not available anymore!”
Are our lives so much subjugated by brands? Ok, now that’s a pretty debatable question.
The reason to blog about this age-old incident is that I googled for this poem for hours, but I didn’t get any information! So, anybody having this short little poem please pass it on. I really want to read it again! :)
