I'm reading a novel, get to this phrase and curious about the exact meaning. Is it an idiom or can I just interpret this phrase as 'trying to do something impossible"? Yes.
While Iím standing there, debating on whether or not to fall flat on my face right here, right now, or attempt the impossible, the back door opens and out steps Grandpa, a coffee cup in his hand. Cool. Grandpaís not dead.
Thanks for your help! :)
