In our office suite, we're very concerned with security. To the point that to go to the bathroom, I have to go out one locked door and 10 feet later, go in through another locked door. (That, or go around the long way. Frankly, I'm like my kids. I always have better things to do than take time out to go to the bathroom. By the time I finally get around to taking a potty break, I'm looking for the shortest route!)
This has been the case for several months now, so you'd think I have the hang of it. But no. Every time I go out the first door, I reach for my key (hanging from a stylish frog clip hooked to my waistband) to open it. From the unlocked side. Oops! Don't need the key to open the door over here! But now that I've almost grabbed it here, I'm sure to remember to use it on the next door. :D
Then I exit the door. 10 feet later (Okay, I don't know the exact distance, but it's very short. It takes maybe 5 seconds to walk from one to the other.) I come to the second door. And try to open it. What! It's locked! Oh, wait... right. THIS is where I was supposed to use my key. D'oh!
But hey, at least serves as a good reminder so that I remember how it works when when returning from the bathroom a few minutes later, right?
So I go out the first door - don't need my key for that one! Walk 10 feet. Try to open the door and d'oh! Right. It's locked. I need the key. Just like I did 2 minutes ago.
