On Friday 13 November just after the start of the attacks, Sylvain Lapoix created the hashtag #PorteOuverte.
If you are in Paris and have a place to stay, let us know so we can retweet it #PorteOuverte— #PorteOuverte (@PorteOuverteFRA) 14 Novembre 2015
The day after, on Saturday 14 November, #PrayforParis is created, rising various reactions among tweeters.
The hashtag #unebougiepourParis (a candle for Paris) invites Parisians to light up a candle on their balcony to pay tribute to victims.
#FluctuatNecMergitur - Paris' motto meaning "Tossed but not sunk" - becomes a resistance slogan.
On Sunday 15 November, Parisians post pictures of themselves using the hashtags #Jesuisenterrasse, #OccupyTerrasse.
