Hi,<br/><br/>I am just wondering about the meaning of "I can't think of it off hand" in the following conversation.<br/><br/>James: Do you know what Herold's phone number is?<br/><br/>Batty: I don't have my address book on me....I can't think of it right off hand.<br/><br/>I think it means that I don't remember or it's out of my hand... or something like that...but I am not sure.<br/><br/>Thanks in advance.
