Noisy mobile phones

I moan about many things, but one that is in my top 3 is people that don't turn off the button sound on their mobile phones. Would you like it if I came up to you and said 'Beep beep beep, beep, beep beep beep beep beep beep. Beep. Beep beep'? No, didn't think so. It grates me even more when it is my mother-in-law, at 5am on a Thursday morning, in my lounge, for approximately an hour. The limit is reached when it is the mother-in-law, at 5am on a Thursday morning, in my lounge, for approximately an hour, when I woke up early to watch the first day of the third test.
