An Obscure Reference to 'The Castle'

This was happening at the foot of the stairs at the Basilisque du Sacre-Coeur at Montmartre. Sara and I were directed here by an old man in a little hat who approached us as soon as we popped out of the metro and gave us good-natured directions in french. We bought macaroons and walked up the hill and a loiterer told me that he loved me.
