Many moons ago I had a Welsh partner who thought I might like to learn to speak the language. As we stayed in Scotland (Kettlebridge to be exact) and she could speak English, as could her parents I couldn't quite understand the logic?
However, I can still say 'croeso', 'hwyl', 'os gwelwch yn dda' & 'diolch'! (hello, goodbye, please & thank you). Unfortunately I didn't progress to the more important phrases, such as 'a pint of beer please' and 'another pint of beer please' before we decided to go our seperate ways.
