W: You look worried, David. Anything wrong with you?
M: Oh, it’s nothing really.
W: Arc you sure? Would you like to talk about it?
M: Well, to be honest, it’s.., it’s my mother. She... she.., how shall I put it? She has been behaving strangely lately. Do you know what I mean?
W: Not quite. How? In what way?
M: Well, you see, ever since my father died, she has been unhappy even though.
W: But that is normal, isn’t it? People are always upset about things like that.

W: Oh, I see what you mean.
M: It wouldn’t be so bad if she didn’t live so far away. When my father retired, they moved to the seaside. Then only a year later, my father suddenly had a heart attack and just passed away. Now she’s all alone in a big cottage by the sea with very few friends and no family near. her.

M: Her memory seems to be going. I have to remind her to do all sorts of things.., to pay the gas bill, for instance. She gets annoyed with me. But I know she’ll forget if 1 don’t.
W: Well, don’t worry about it too much. She’s just getting old, that’s all.
M: I know. That’s just the problem.
