If you're still hiding your cigarette smoking habit from mom and dad every time you go home for the holidays, you might need to work at being a bit more covert so you don't get the third degree when mom finds a lighter in your pocket. This might look like a cell phone, but it's actually a butane lighter. So sneaky!
It looks like a DoCoMo phone, which, unless you're in Japan, isn't that common, but I'm going to go ahead and assume your mom isn't as up-to-date with the current phone market as you are. Oh, and there's another option: quit being such a wuss, tell your parents you smoke and to deal with it. It's cheaper, less sneaky, and you won't have to worry about explaining why you carry around two phones.
