I don't understand the meaning of this: ''One of these characteristics is that the feeling cannot be brought on by appearances, and must gradually develop between the two people as they get to know one another.'' Any explanation?
Thanks for your help Casiopea. But i still don't know if i've understood well.
So...: Appearances won't cause those feelings. And...that would imply that : Feelings won't be caused by appearances.
Am i right ?
