Locked

out!
I work at the local Christian Radio station here in Joplin. Its called KOBC. I have been working there since i got to Joplin, so its been 4 years. I started out with an afternoon shift on their spanish programing. Then i moved to the dreaded weekend shifts. and now this semester im working the evening shifts (6pm to 12am) two nights a week.
normally when i come home Katie has already gone to bed hours before. She works early in the morning and therefore goes to sleep at a decent hour. So tuesday night i come up to the door in a very very good mood (especially considering how late it was and how tired it was) only to find that the screen door is locked from the inside. we have the lock there so that we can close the screen and open the door but people still cant just walk in. This strategy was great for the nice fall days that were cool and we saved some energy by not needing the AC.
Im standing out side our door with no way of getting in. So i think to my self, "now what?" I try calling Katie's cell phone hoping that she has it with her in her room. but as i stand out side i can hear it ring, and see it light up on the couch in the living room.
With no other option i go to the back of the house (which is quite dark and scary at night) and knock on Katie's window saying "Katie wake up! you locked me out" the reply i get is "huh?" so i repeat "its me Megan, you locked me out" and she then says "oh ok"
then nothing
so i stand there for a minute debating with myself as to wether she actually woke up enough to understand or if she was just answering in her sleep. i decide to go to the front door and wait. a few minutes later Katie opens the door and says "i dont know how that happened, i didnt do it". a coment to which i answer with "then who else is inside that could have locked the screen from the inside" and she replies "i dont know but it wasnt me".
in the end i walk to my room laughing and Katie is walking away to her room in a frustrated voice saying "i dont know what your laughing about it wasnt funny!"
ahh roommates. gotta lov'em!
and Katie if you read this and dont remember it. its ok.
