W. All right. M: Ah, ah. Would you like a cup of tea？ W. No, no, I'm fine. M. All right. W: Thanks. M. Well, could you describe the two people who robbed the bank for this report we're filling out here？ Now anything at all that you could remember would be extremely helpful to US. W. Well, just, I tell you I remember basically what I said before. M: That's all right. W: The man was tall, about six feet, and he had dark hair. M. Dark hair. W: And he had a mustache. M. Very good. All right. Did he have any other distinguishing marks, I mean, scars for example, anything like that？ W: Scars, no, none of that I can remember. M. Do you remember how old he was by any chance？ W. Eh, well, I, I guess around thirty. M. Around thirty. W. Maybe younger, give a take of a few years. M. All right. Do you remember anything about what he might be wearing？ W: Yes, he, he had on a dark sweater, solid color. You know, the kind of color young people fancy nowadays. M: Anything else that strikes you at the moment？ W: I, I remember he was wearing a light shirt under the sweater, a cotton one with dark, I think, dark stripes. It looks like a good brand. M: Ah, very good. W: Yes, yes. M. Mm, now, all right. Can you tell us anything about the woman robber, Mrs. Harrison？ W: Well, I remember that she did most of the talking. She had a gun pointed at us and she told us to lie down on the floor and not to move if we knew what was good for us. I, I remember I've just thought like she was pointing the gun right at me and my little daughter was sitting right next to me and she, she was just so frightened. M. Um, Mrs. Harrison, could you describe her for us？ W: She was wearing a wool sweater. M: Ah, very good. W: I remember it was a dark color, navy blue or dark gray. M: Dark gray？ W: And I guess she was in her late twenties. Her hair was short, very short and curly. M: Do you remember how tall she was？ W: Ah, about the same as myself, around five four. M: Five four. All right. Do you, uh, remember anything else about this woman？ W: Yes, I remember the woman was wearing a pendant or a locket around her neck. I remember it specifically because I was then near the counter next to the bank manager and my little daughter started to cry. M: Ah. W: And this woman came up and said: "Shut your damn kid up, lady!" So I got a good look at her and she was pulling on the chain and playing with it, a pendant. M: Oh？ W: It was gold, well, anyway, lookes like gold. And it had a strange shape. M: Mm, ah, now, did either of them have any other noticeable characteristics, Mrs. Harrison？ Now, just take a minute. W: Eh, no, I don't. M: Think about this. W: No, no, this is really all I can remember. M: Well, did either of them wear glasses？ W: No, no, I'm sure of that. M: All right, Mrs. Harrison. I really appreciate what you've been through today. I'm just going to ask you to look at some photographs before you leave if you don't mind. It won't take very long. Could you do that for me？ W: Ah, all right. M. Would you like to step this way with me, please？ W. OK, sure. M. Thank you. What strikes the woman most about the male robber is his A．clothes. B．age. C．physique. D．appearance.
