Double bonded oxygen and aromaticity

When you see double bonded oxygens inside rings, you have to imagine them ripping those electrons out of the double bond between it and carbon. Then rearrange the ring accordingly. Don’t be surprised if you end up with a charge separated resonance form that looks aromatic. It probably is.
