I just put my mother on Air France for her first ever trip to Paris. At 82 it's best not to delay, even if she is in good health. Mobility counts too, and might make her less able to travel in the future.
My French-speaking brother insisted it was his responsibility to show her Paris. So she and I resisted severe temptation while in Europe. Look, it's the Eurostar, Mom, we could be in Paris in only 2 hours! But no, it wouldn't be right. Must wait for my brother.
And in my case such a trip would have been my first experience with the tunnel between England and France. Imagine what the warriors of centuries past would say about a tunnel under the English channel. Hey, let's invade this morning!
Mom and I have had a roots trip to Germany, where we saw people that look like various relatives; a lovely tour of Britain including my beloved Scotland; and a train tour of Italy and Switzerland. I am grateful to have these times with her. The experiences remain high on the list of my fondest memories of the last few years.
Bon voyage Mother! Wishing you much joy on your journey. You sacrificed so much to bear 8 and raise 7 children. You deserve all the happiness you can get.
