My Mom spoke Welsh quite well when I was young, but by the time she died, she had forgotten it. However, during her last days in the hospital, when she was more or less incoherent, she started speaking it again, seemingly fluently.
My mom and dad were both Welsh. Dad from Tonnypandy/Pennycraig area, and my Mom from Kidwelly, near Carmarthen. I've been a number of times. I like it, but, between you and me, it is a weird little place.
I tried teaching myself Welsh at one point, but there aren't many Welsh speakers where I live. Which part of Wales are you from? Are you still living there?
"Keep your thoughts positive,
because your thoughts become your words.
Keep your words positive,
because your words become your behavior.
Keep your behavior positive,
because your behavior becomes your habits.
Keep your habits positive,
because your habits become your value system.
Keep your values positive,
because your values become your destiny."
