Spotted...

I was mildly amused when you quickly hand over your expensive (I think) Canon HD camcorder for a few second just to show me your sign language considering you never met me before!

Yep, well remembered, Canon HD and yes very expensive !! What can I say, you have a trustworthy face !

your sign language is a BSL - British Sign Language, and yes there's more than one, it's not surprising that the American have their own as well, which when a deaf American signed to me once in Las Vegas, it's as if he's speaking fucking french to me.

How did you know he wasn't French !!!?? :D

anyway it's nice to meet you, I knew it's a good idea to find out what bike you have before going out back in London again, was in a rush cause I was late meeting my girlfriend in Russell Square!

You know you look like an undercover hipster Police Officier using your camera as if it a speed camera flagging down cyclist who's breaking the speed limit (or HHSB limit).

Yeah, I am amazed at how many people scowl at me - I think they think I am clocking their speed like you say. I might buy a helmet and truncheon from the toy shop to finish off the look.
