All along the life, we let the sense of linearity fool us. It is deeply ingrained in our perception and we are not even aware of it most of the times.

The world may or may not run in line. We will never know, because we never live long enough to figure out the true trend. But our emotions don’t run on a line. They run in circles, cycles. They shoot up, then they max out and mostly they recede like a parting tide.
