I got home the other day. Took a shower, ate, locked the door and started to gratify myself when I heard knocking on the door. I was not going to answer. What I didn't know, though, is that when I came home earlier, I forgot to take off the keys of the doorknob... So as I'm confidently ignoring the knocking, the door opened... Damn!
I'm telling you this though: I am never...
...forgetting my keys again!
