I SEE ME, or my evil twin brother in the glass door incident. Darn, I just hate visiting people that are so squeaky clean the windows disappear in their house.
It comes down to a choice when one has 4 little kids running about when it comes to sliding glass doors. You can let them get dirty with puppy nose spots and baby hand prints, or keep them see through clean and put a few stickers on them so you and the kids don't boink your heads thinking they are open. Helps with pets also, when dog chases cat and cat dashes for an open door way to find it is not open, then when one stops laughing do you do CPR on the cat.
Yup I have had some interesting encounters with glass doors not to mention stairs while wearing high heels, a few problems with escalators -------------Living in the boonies has this effect on us who only ride an elevator when at the hospital.
