When I was in high school and college, I would stay at my friend's house when they were on vacation so I could watch their dog and cats. Their house was in a pretty quiet neighborhood, but for some reason none of the doors on the inside of the house had locks on them. Bedroom doors, bathrooms doors, NO LOCKS! Who doesn't put a lock of some kind on a bathroom door!? I can see a bedroom door maybe, but not the bathroom. What if you are in there and someone just walks in?! How embarrassing!!

Here is a solution that you can take with you wherever you go and all you need is a household fork. Preferably one with a slim handle on it. How does it work? Check this out!
