I want to be a Welsh speaker because it's been a lifelong dream to regain that part of my heritage and be part of keeping the language alive.
That's the primary reason, but I discovered another reason just a couple of weeks ago when I told my sister I'd signed up for the Six Months Welsh Speaker course: she actually thought it was wonderful! This is a big deal because we've never got on very well and she's spent decades disapproving of everything I do (we're both in our 60s). To have her now applaud something I'm trying to do is a sensational thing!
One thing I hope will happen when I'm a Welsh speaker is that I can go to gatherings such as the North American Festival of Wales and not have my single Welsh sentence be, "Mae'n ddrwg gen i, ond dw i ddim yn siarad Cymraeg" (I'm sorry, but I don't speak Welsh).
