Locked out

I was at my sister Boopie's house last week to help her move a weight set downstairs and I guess she put a fence up outside her side door. I actually complimented her on it a little after I got there. My mom, my brother-in-law and Boopie were taking apart the weight set and I didn't have anything to move at the moment so I figured I'd let the dogs out and have a cigarette. So I went into the parlor, grabbed a cigarette, and lit it. Then I realized "Duh! They don't smoke in the house!" I had to run through 2 hallways to get to the door to let the dogs out. So I run out there, and I'm all flustered. I shut the door behind me and I hear a click. Shit! That's the door that automatically locks. I looked around, and there's no gate in the fence. I figured "Oh well, I'll just knock when I'm done with my cigarette." So I finish my cigarette, get up and start knocking on the door. Well, boopie has a huge house and everybody was upstairs...on the other end of the house. So I knocked. And I knocked. And I knocked. I was stuck outside for like a half hour. With nothing to do and no cigarettes. Eventually, a fedex truck pulled up in front of the house. I knew somebody would be coming down to get the package (since THAT door is right next to the staircase they were by) so I started knocking again. Luckily, I knocked at the right time and my brother-in-law saved me.
