We often hear "oh we don't speak that here".
Oh but you do, if we look at:

-The place-names you say
-Your pronunciation
-The grammar you use
-Sentence construction
-The speed you speak at
-Word shortening

The medium might be English; but Welsh is under the surface...

@wenhwyseg my brother often points this out to me as well
@wenhwyseg If your friend is your butty, you speak #gwenhwyseg !
