Have you ever seen an adorable puppy and imagined yourself squeezing it way too aggressively? Don't worry, you're not alone.
Even though most would never admit their "psychopathic" desires out loud and would (hopefully) never act on them, they probably have at least thought about toeing the line.
So don't feel bad about your overwhelming urge to kiss someone out of the blue, for no reason at all.
Just, probably, don't do it.
