Quite a nice, breezy opening . Feels very chick lit – not usually my sort of thing, but decently written. The structure works well, with the nostalgic, summery opening contrasting with the wintry feel of the remainder. It would benefit from a little grammatical tidying up, eg repetition of Champs Elysees in the opening paragraph, might [have] been my supervisor , and the use of quote marks is also slightly haphazard.
