Did you read ALL my post
"Because I don't nod where it would be inappropriate, where it would be inconvenient or dangerous to return it
"
I've been riding almost 50 years
Don't you think that by now I've worked out where it's safe to nod
As for "why" return a nod
Because it's "common courtesy" that's why
It's like saying good morning to someone or good evening
And them totally ignoring you
Would you like it if you said "good morning" to your nieghbour and they just "blanked" you
It is just good manners
