PLEASE HELP I BEG YOU!!!
The Metro is tricky in France. Each line has a starting point and an ending point. When you get on a metro line - you are going in either one direction or another. Say you were on La Ligne 8 - it goes to either Balard or Creteil / Pointe du Lac.
EXAMPLE ↓
I will show you how to go from Bastille to Pigalle...
If you are at the Bastille and want to go to Pigalle:
Take Line 8 (toward Balard)-
to line 4 (toward Porte de Clignancourt),
transfer at Strasbourg Saint-Denis-
to line 2 (toward Porte Dauphine),
transfer at Barbès Rochechouart - arrive at Pigalle.
Choose one of these destinations from Bastille. Show how you would navigate the Métro (just like the above example) to get to:
