It can't get more instant than this.
Last week, our geyser was under repair and we had to heat water on stove for a few days.
One afternoon, my super lazy sister patiently heated water on the stove, carried the water bowl to the bathroom, poured hot water into the bucket and went to the balcony to get her towel hung to dry.
I took advantage of the situation and rushed to the bathroom to take bath using “her hot water”. She came back and discovered what had just happened. She banged on the door but I refused to open. I was devilishly laughing for her fate and my luck.
As we were screaming and swearing at each other, the door bell rang. Mom asked us to shut up and answered the door. I opened the tap but kept my ear pressed against the door so as to guess who had arrived.
I heard our security gaurd asking mom not to use bathrooms for a while as the overhead tank was being cleaned and he also instructed mom to keep the taps open so that the dirty water flushes out.
It took two seconds for me to react. I took a turn and looked at my bucket of “stolen hot water” getting filled with brownish dirty water from the over head tank. It felt like an invisible chappal flying and landing on my cheek.
I opened the door and my sister was dancing in ecstasy. Dinchak da da dinchak daka da. My mom had the best laughter of her life.
Karma, just be yourself. Don't spare anyone. Love you.
