Well, when my "better half" stops talking on the intercom, then I know, soon her helmet will knock against mine and she will fall asleep - time to reduce the pace a bit... That happens normally more often after a good road-side meal. In such cases I move a little backwards on the seat, lean a bit forward, she takes a nap and I have a quiet hour or so...

Not that bad to have an intercom. You'll learn to enjoy the beauty of silence more then.

Cheers,
AW.
