.........Misplacing your phone and just plain old not recognizing what that annoying sound is, coming from your pocket.....which is worse?

I haven't lost my phone lately, but have managed to sitt and listened to the ringing sound...wonder why the TV would have such a sound coming from it....or just the other night, was sitting with the phone in my pocket, it starting ringing AND vibrating and I still didn't know what it was....

It must be old age......
