Bizarrely,
she doesn't seem to mind changing her mind at the last minute even if she does have to pay. The concept of booking train tickets a reasonable length of time in advance in order to get a decent price and thus save money, for example, is completely alien to her. Going to Berlin on 25 December? OK, let's get the tickets on the 24th.

Part of the problem is the fact that she has a different notion of the value of money to most of us: both her parents are loaded, and her grandfather was seriously rich, so despite her unspectacular school career and series of very modestly-paying jobs she bought her own flat in cash in her early twenties.
