About 10 years ago my family moved house about 30 seconds from my old house (liked the area but wanted a bigger house). On Christmas day, not long after we had moved in, my grandfather walked to our house to visit us. At the time nobody knew but he was suffering from dementia. He went to the wrong house because he couldn't remember where we lived. Luckily for me, my family and my grandfather we live in Scotland where it isn't considered acceptable to shoot through a door at the slightest sound, otherwise we could have been dealing with a tragic situation on a day that should be a happy one.
This isn't a criticism of the woman in the story, it's a criticism of the full grown men in this thread that find it acceptable to shoot wildly through a door at the first sign of trouble.
