I had lunch with an old friend that has to have had a stroke. I couldn't understand him. It is hard seeing someone in that shape. He couldn't read the menu. I can't believe he is allowed to drive. Most uncomfortable 1 1/2 hours I could experience.
I recall a customer that had a stroke,his speech was very difficult to understand as well. He as a good customer, but had some struggles. His driving was fine.
I wonder if your friend had any treatment or not.
