Nothing but my iphone

The thing that annoys me most is having to carry things with me. Because I am such a forgettful person, I have a problem with leaving my things in public places. My phone is one thing that I usually always carry with me, but there have been numerous occassions where I have had to call restaurants or stores because I left my phone there. If I ever feel the need to carry money and whatnot, I typically bring a bag because it is much easier to see that as I am leaving somewhere. All in all, I dont like being responsible for extra items when I leave my house.
