Literal emotions.

If tears crystallized on our face, no one would ever dare to cry.

If happiness made us crack a grin, no one would consider smiling.

If anger stayed etched on our forehead, we wouldn't bother being mad.

If joy left us in stitches, we wouldn't care to laugh.

If fear glued our eyes shut, children wouldn't quake.

If excitement blew our mind, men would never venture.

If hate boiled our blood, women wouldn't berate.

If love struck our hearts, we'd always be apart.

Never start.
