The Shard is south of the river. I sympathise. I get very antsy when I cross the Thames.
One of life's mysteries it's unexplainable, I hear tell those strange others that live on the wrong side of the Thames feel the same about people like us that live on the right side of the river.
Can't give a logical or rational reason why, I can only say south London feels wrong all of the time you're there.
