I was in a bit of a hurry when I got out of the elevator to go for my walk tonight. There was someone right behind my carrying an armload of things, and there was someone I recognized as a resident trying to get into the building, so I wanted to be able to open the door for both of them.
In my rush, I completely missed the latch of the door and walked into it instead of opening it. Smooth.
Oh, if only that were the first time I've walked into a glass door today. Alas.
