White Boarding. Habit to write anything on white board and discuss. White board discussion is common for any office environment. But outside office I doubt it.
In home,
When my mom asked what to prepare for lunch? By mistake, I took marker from my bag and started to use big mirror in my home as white board listing all items needed and started to give a logical explanation why we need all this ? to have a minimal viable lunch. My mom went crazy and told will make sambar :(.
In car,
When driving car with a friend when we started to discuss on some topic. I just stopped vehicle grabbed the marker from my bad and started to draw on my car window glass explaining him.
In train,
While travelling back from Bangalore happen to meet a business man. We discussed number of topics. Again to explain something just took a notepad and marker, then we had long conversation.
I don’t know whether it is strange. People involved looked at me like strange guy.
