Writing from paris T7 line, that takes us from our respective locations to Orly Airport.

Hmm... Orly?

We can count 11 occurrences of the name Orly on this plan. Most are distracting, but at least one of them “Pont de Rungis Aéroport d’Orly” is seriously misleading (as it is written in a taller font than the one used for the correct stop).

And may be you can also science-fictionally walk to Zone 4. Don’t get lost there.
