You have been neglecting so many of the more important areas of your life dont you think?
When was the last time you had any proper fun?
You dont think you could possibly be hallucintating? Dont even get me started on the amount of coffee your consuming...
Alternatively maybe I just moved in nearby and noticed you rattling around the house on your own and thought I could have a little amusement by letting myself in the back door that you left open and playing some games with you?
