I was certain you would bite 
Oh, I think I didn't bite, but merely responded; I know an angler when I see one... You'd notice if I bite you!

However, contemplating "biting responses" together with your remark
See you in Amsterdam in June.
and the very subject of this thread I could say the following
You have put various photos of yourselves up on this site, so
I know how
you look, thus can recognise you in June if you come. You will not be able to find any photo of me anywhere on the web, so
you will not be able to recognise
me if I am there. Imagine the following speech by yours truly:
"Did you enjoy that sandwich I gave you an hour ago? Ah, good! By the way, I'm the guy you know as "gep". Did you know I work in microbiology? Amazing what kinds of bugs I can postorder for my work! Some are very
interesting you know! These things come in small handy pills you wouldn't notice if somebody put them in your sandwich! What? Oh, ehm, I think through that door and then to the right!".
The kind of bite that sucks, eh?

(sorry, no emoticon for "satanic hollow laughter")
yours truly,
hope to see you in June!
