One day you were casually walking around the mall when you passed the local gardening shop and heard a conversation between two employees: "Yeah, the man insisted he did buy the plant here even tougth we had no records of it! Why does one even return a plant anyways?"
Being interessed you decided to take the so called plant home, it was tall and had beautiful leaves. You had never managed to take care of a plant but you were full of determination; you watered it, gave it sunbaths, even talked to it.
Then one nigth, you heard an noise down stairs, like if there was someone moving around your home, you armed yourself with a chair and creeped up on your living room. You noticed there was nothing missing, nothing but the plant, yet, the door was closed, no broken window, it was as if whatever was walking around had already been in your house before you went to sleep.
As you turned around the corner you saw a figure of a person you didn't reconize trying to climb the kitchen counter and open the window.
