Sorry forgot a couple of points... shops will be closed on Bastille Day and the fireworks kick off after dark around 10ish. Trocadero is the best place to watch them but people start congregating there late in the afternoon / evening so it will be busy busy busy :o)
DÃ©jÃ  vu (/ Ë d eÉª Ê ÉË Ë v uË, - Ë v j uË / ( listen); French pronunciation: ( listen)) is the feeling that the situation currently being experienced has already been experienced in the past.
The most likely candidate for explanation is that dÃ©jÃ  vu is not an act of precognition or prophecy but is actually an anomaly of memory; it is the impression that an experience is being recalled which is false.[citation needed] This is substantiated to an extent by the fact that in most cases the sense of recollection at the time is strong, but any circumstances of the previous experience (when, where and how the earlier experience occurred) are quite uncertain.
