WhatsApp now has blue ticks to indicate that a message has been read, with each message also displaying the exact time that it was read. I choose to not feed my own insecurities (of which I have plenty), and commit to not to judge based on the blue ticks, and to not check the message read time. Same goes with Facebook messages, I guess.

The presence of a feature does not require or imply a need to indulge it.
