Today, I reacted to a behaviour from another person, totally, in a different manner, as I would have reacted to the same behaviour a year back. Perhaps, I changed the way I looked at the behaviour and forgot to tell the person who initiated it. This resulted in a lot of surprise and diasappointment for both of us. I heard comments like"This is not you"

I had to explain myself and try to talk myself out of the behaviour, which was not very effective.

What I learnt is that one needs to examine one's way of looking at various things periodically. All of us change, most of us, silently, and we often forget to communicate to other people around us. Communicating upront to people around us will save us all a lot of unpleasent surprises.
