I agree with rif, thank her for the shirts, and don't mention the papers. If she does. Don't tell her that you are waiting till you return. String her along by telling her you are thinking about it. No other reply. Why? Because you want her to continue to open your e-mails hoping that you are going to agree to it. This way she will keep contacting you. And you are in control of the communication. Eventually getting her off the subject and on to some LB building conversation. Just a thought.
