Don’t understand the post, but here is my way:
anyone I see on a bike I’ll say hi to, give or take 😉
anyone I catchup with, depending on their pace I’ll have chat with them before saying ciao, unless they want to do a bit of through and off.
Half wheeling is the worst thing though, caught a guy at some lights the other day, he was on a Cervelo so you can already imagine what he’s like (think Audi driver), he didn’t remove his headphones so couldn’t hear me when I started talking, he then just rode along side me pushing harder and harder with the speed getting higher and higher…clearly a fool
