Present

I forgot to tell that a few weeks ago I suddenly got a package by mail. Strange shape in an envelope and coming from the Czech Republic. Lucie told me that she wanted to send me something for my birthday and she send me something lovely. I got a very nice pair of cufflinks for my shirts from her. Now I am deeply in debt with her, since I still haven't visited her in Prague and didn't buy her a birthday present. How to make it up?
