I worry about losing my cell phone. I pat my pocket to make sure it's there whenever I get out of a cab, stand up from my desk at work, leave my house, or walk more than 10 feet. The other day I was talking on the phone and I tapped my pocket and then panicked for a split second when I noticed that I'd lost it. Then a second later I realized I was holding the phone in my hand and shouting into and I relaxed, only to have a minor freak out 10 feet later when I tapped my pocket again. Some people might call me neurotic.
