Back to the woman who knew how to sell Marc J's. I went into the store, had a couple wrapped up and then I found out I forgot my wallet at home.
When I got home, I told my sister that I was going to buy her something, and that she could choose between the following two options, not having any clue whatsoever as to what I would buy:
a) I buy, you pay, I bring you a birthday present from Milan.
b) This will be your birthday present.
She decided to pay, and when I came home she was quite happy. Besides, they were 50% off (and there are more pairs at Den Dama, Lapsetorvet) and since she probably never would have found them herself, I consider it a nice favour... now what to get her from Milan?
