Unexpected Intruder Investigation

Okay, so this happened last week, and my friends keep telling me to post

it, so here we go. My neighbor—let’s call him Mark—went on vacation for

two weeks. Before he left, he told me: “Hey, if any packages

come for me, can you grab them so porch pirates don’t take them?” Cool,

no problem. Except… on day three, I hear a loud crash from his house. I text him,

no reply. I knock on the door—silence. Then I notice his back window is SLIGHTLY open.

Now, a normal person would call the police, right? Not me.

No. My brain said: “Break-in? Ghost? Cat burglar? Go investigate alone.”
