Arggghhh I want to go outside :/

It's all nice outside and I'm inside laying on a bed. I can't go outside without the risk of getting locked out because I don't have a copy of my grandmother's keys. Plus, she usually calls the house around twelve so I have to wait till then or she'll think I was kidnapped or something. So what can I do if I decide to leave... I could try to hop the fence in the backyard but people might think I'm trying to break in and call the police. I could see if I could find a way to keep the doors unlocked but make it seem like I locked it, possibly not the greatest idea since my grandmother is super paranoid about someone breaking in. I actually might go on a bit of a scavenger hunt for an extra pair of keys hidden somewhere in this place because, who doesn't have an extra pair of keys somewhere in case they lose the original? I also want to let the people of Virginia know that the guy who has been inside 10/14 days of his stay here so far, is finally going outside!
