Is it weird for a European to not travel to other countries?

My aunt from Vietnam married a Frenchman and has lived in France (a commune near Strasbourg to be more exact) with him for 6 years. She has never been to Paris and has only been to 2 other European nations -- Germany and Switzerland. Heck, I'm American and have been to Paris, so I don't see why she hasn't. Countries in Europe are relatively small, compared to U. S. states, so it's normal for, say, someone in Germany to take a day-trip to the Netherlands or someone from London to take the Eurostar to Paris. 6 years is more than enough time to go from Strasbourg to Paris -- like less than 3 hours by car.
