Liquid theft

Someone drank my vodka!
How dare you?!
Could it be my mom? Unlikely.
Could it be my dad? Possibly.
Could it be my sis? In between unlikely and possibly.
Could it be my sis's bf, the Roach? I hope so, then I'll have a good reason to spray Ridsect on him.
After that, I'll shove his dead body into my sis's mouth, and hope she choke to death.
Yeah! Muahahahahahahahah!
