I’ve done the kiss blowing thing before, it’s brilliant fun.
I was in a car leaving the M5 and due to the time of day, there was a queue leaving the motorway, I was slightly caught out by the length of the queue, so needed to spot a gap.
Gap spotted, I pulled in behind a white estate car, at which point the driver looked in his mirror and went nuts! No idea why, but he was flailing around and shouting a lot of abuse at me while staring in his rear view mirror.
A few yards on the exit split into two lanes and I wanted to turn left while 90% was turning right, including Mr Heartattack. I drew alongside, he wound down his window and was red in the face and screaming… so naturally I blew him a kiss, and drove off.
Ohh, what fun we had.
As for giving blank looks, I’m deaf in my right ear and wear a hearing aid, if a car goes past and someone shouts (rare, but it does happen), I can’t make out what was said, so they all get a slightly bemused grin.
