H.G. Wells' Invisible Man

Sally: If I do my exercises every day, will I grow up big and strong like you?
Peter: I expect so, Sally.
Sally: I wish i could grow up to be invisible.
Peter: You'd never get married.
Sally: Why not?
Peter: Well, umm... that's all for today.

Crowther: What's the matter, Sally? Why are you looking at me like that?
Sally: I was just thinking...
Crowther: What?
Sally: How much nicer you'd look if you were invisible.
