Fool me twice

I no longer believe I dropped my wallet on Wednesday. I think there was a thief in my building.
Why? I am embarrassed to admit this but once again my wallet has been emptied of its cash. It happened between 2:00 am and 6:50 am today. This time the robber left my wallet on the table in the genkan, but I don’t sit my wallet on my hat so I noticed right away.
Now what? Aside from being more diligent about locking the door and keeping my wallet far away from the genkan, I will go to the police and report the thefts, alert the building security, and post a notice to warn the neighbors.
So much for my complacent feelings of security.
