Where are my pyjamas?

A man calls his wife and says to her, "Honey, I just got the chance of a lifetime to go on a week-long fishing trip with my boss. Could you pack up my things so that they will be ready when I get home?" "Sure, honey," his wife answers."Oh, and could you please pack my blue silk pyjamas?" "Sure, honey," his wife answers again. The man comes home, picks up his things and takes off for the week. He returns a week later, smiling. His wife greets him at the front door. "So honey, how was your fishing trip?" "It was great..." the husband answers. "But you forgot to pack my blue silk pyjamas." "No I didn't," said his wife. "They were in your tacklebox."
