You know what sucks? Going outside when it's really cold. It's made worse if you don't have a jacket. And then, when you go back inside to get your jacket, you find out that you locked yourself out of the house. So you go to unlock your door, and realize your keys are inside. So you knock on the door, only to realize that you're home alone. So you go out in the backyard to get the spare key, to find that it's not there anymore.
...I just got back into my house, and I don't even remember why I was outside in the first place.
XD The only way they'd be able to see is if they were like on their roof or in their attic... Pyro?. I use my bedroom window, in the backyard, it's the easiest entrance (not that I want any of you using that as an entry point.)
