Recon Number 54 -
If they are still looking, then while holding the snarl, I let drool start to drip from my mouth, I stand, curl my fingers into claws and with a hunched over crouch, I then make slow and deliberate steps towards them. When I get close enough, I let them hear my agonized and gasping growls and then, if they continue to stare, when I get within arm's reach? I kiss them on the nose, and run away giggling.
