Hm... I'd have to say, when I got my first cell phone. I was playing Mass Effect, and my mom came in and placed it in my room and then called it. I was too busy playing Mass Effect however, to even notice. Oops. Sorry mom, you don't interrupt a great game >.> It was pretty cool though, because at the time I was dying to have one like all the older kids. And now I hardly use mine except for music.
