Don't nod because you expect a nod in return
Do nod because you're having fun on your scooter, you want to express the joy you feel & life is good!
Who cares whether you get a finger, a shake of the head or no response at all? If they give you any of these then laugh at the buggers because they're so precious & uptight.
I'll nod or wave to anyone who shows any interest in the scooter. I love the scooter, I love riding the scooter & I love expressing the enjoyment that I get from riding. I'll often find myself grinning from the moment I leave home to when I arrive at work because, once you overcome the economics & ease of it, this scooter riding is FUN!
Now to be found "working" at Ace Scooters (sales, accessories, coffee maker, dish washer, gopher and general stirrer).
Currently riding a Vespa GTS250ie. Hopefully this will be the last time I upgrade. For a while atleast.
