Just try your best is my advice to anyone, hand gestures and most of all smiles and a modicum of good morning's, please and thank you's is a good start, try adding a new word a day.
My husband has found his own unique way of learning as he finds an english word that sounds almost the same - eg My farm - becomes Ma Femme, cushion becomes cochon (very important to us these animal words); but it is working, so much so that after week two he was safe to go alone into the outside world as, at the time I was not too well. When I was back at the wheel and able to travel to the local village, I was questioned on the whereabouts of my husband as they love him to bits. His charade of "honey" is still apparently the talk of the town (involves a pot of jam and lots of buzzing and him saying "meal" a lot).Have fun with the language, he has grasped it so well in the last six months, that he can understand and follow the majority of a conversation of what is being said, even when I am around to translate her prefers to manage. I am so proud of him for making such an effort. a
His 93 yr old mum has lived with us for the past 5 years and came readily with us to France. She too, is well used to saying "Bonjour", and a few basic phrases and has developed a lovely accent. Mind you she loves all the "bises", and thinks Frenchmen are wonderful. I would use the excuse of her age, but she has all her faculties, succumbed to her first pair of glasses this year and even has all her own choppers so she knows exactly what she is about, as she pauses for her greetings everywhere we go. We even parked her in our local bar while we went to the butchers,only to find her surrounded by the locals on our return, I think she was sorry to see us back so soon. (Then they all got to bid her goodbye in the usual fashion - had to drag her away in the end).
