Just a wholesome observation about greeting gesture
I usually greet (two fingers down in general, but it's not a religion). and i seem to notice patterns sometimes. Like vespa riders and electric bikes, i'm not always sure if they know what i mean because i bet most riders don't greet them. Yesterday i put my fingers out, and this delivery guy was just puzzled. He was wearing a full face helmet. But his eyes, and shoulders and head movement said everything. I could literally see a speech bubble saying "Why does everybody keep pointing at the road in front of me?"
