I must go now. I must leave this house for a while. I don't like night-time crooks. What do you think?

I will leave this house. I will go to a nightclub. I want to dance with the girl. The house is neat and tidy but I am wondering if I leave the lights on or not. Would it be easier and safer to safely enter my house if the lights are on? Or is it better to tell the neighbour that I am leaving and to please keep an eye on my house? How do you scare away a night-time crook? What do you think?
