Actually, its Hallo, or Bonjour.
One of the super cool things I found out in Belgium is that depending on the area and city, they speak either Flemish (a form of Dutch) or French. Even the cities and historical sites had two names plastered on signs, one french and one dutch. Since Christopher was in school, I spent a lot of time in Belgium traveling alone, which can be very good for the soul, or it can be terrifying (especially as a woman).
