Context: I tried to get him to agree to show me around the old town but he said he had to go see an old college friend of his sisters , which struck me as a bit weird , who befriends their sisters college friends ? We talked about it a little bit but he kind of dashed off to talk to Ms Calendar . I do n't think it was something I said .
