Fit the key in the lock…

Check this out. I know it’s in another language but as near as I can figure this is what it’s about:

At a 0% blood alcohol level it’s easy to unlock the door, but each time you successfully put the key into the look you get more and more intoxicated. At 2.0% it is nearly impossible. Even after having had all the practice I have I couldn’t get the key into the lock. Another night outside on the stoop.

UPDATE: I got it!
