The first thing I must say is how kind people are. From the taxi ride from my house to the train employees to fellow passengers to random travelers in Montparnasse. All those people were exceptionally nice and helpful. Helping the single mother traveling with two children carry bags and navigate stairs, locate misplaced train wagons, conquer escalators, and find bandaids and disinfectant wipes when Boy2 fell and was bleeding from both knees.
Seriously, don't believe anything bad you hear about the French.
