Dysgu Llydaweg neu beidio dysgu Llydaweg/learn Breton or not to learn?

Jean-Baptiste and myself were shopping when an elderly lady I’d just helped for something started speaking Breton to me. She thought I was speaking Breton with Jean-Baptiste and looked quite excited. But I disappointed her by explaining it was Welsh, and I couldn’t speak Breton.
We’ve been wondering for a while whether we are going to learn or not. The Breton speakers we’ve met are very negative about the language. One said that he wouldn’t speak to a learner. But the experience today was encouraging. Maybe we’ll give it a go.
