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 . Oh , I gave Annabelle a ring too , wanted to check that everything was OK back in da hood and all that . Sounded like she 'd been hitting the tea and was in danger of slinking back in to UK time .

Question: What 's a possible reason the guy wanted to see an old college friend of his sister 's ?
Answer: Because they talked about it a little bit .Because he is interested in her .Because he agreed to show the writer around the old town .None of the above choices .
