I have a very limited hand gesture vocabulary now I come to think of it. The only time I use hand gestures is when I'm driving and the numpty in front of me suddenly decides he's going to turn without indicating. Or pull out into the stream of traffic without indicating. Or suddenly anchors up to reverse into the space he's just spotted a few cars length back. Other than that.... nope! 
Just had to put on a cardigan!
Is it normal to talk to yourself?
. 
to see how many of M's gestures were identical to his fathers!
