I know "It's impolite to sit down with your elbows rested on the table." is correct, which just sounds pretty well to me, but I had also seen some sentence like "AUDREY is sitting on the floor of her room with her back resting against her bed." (Source:Resting Sentence Examples. I added "with" in the sentence myself.)
So if I use "resting", then the sentence becomes:
It's impolite to sit down with your elbows resting on the table
But some how it is strange that both "rested" and "resting" are available in this sentence with the exact same meanings, so I am confused here.
Cautions edited: the source provider of "It's impolite to sit down with your elbows rested on the table." told me that it is more appropriate to use "resting"
So "rested" might be wrong now... but is it wrong? (Consider it as "being" rested by me?)
