Etiquette Help

[Trek420]

He seems like a person who would be interested in stories of the artist/background to the piece of artwork.

Just had an idea. Could you hand him a book? "yes, yes it is a nice wooden fragile hand made owl, isn't it. And HERE, here's a book about the artist. Sit, read."

Another etiquette question; how do you respond when asked if you have an "extra" bike to loan .... to someone you don't know .... or know how well they ride .... for several months ... and you know it won't be secured in the home

Is the answer;
A: "no" or...
B: "he]] no. But thank you for thinking of me and here are some affordable shops thank you very much".
