I'm sorry if I've upset people - I obviously haven't meant to. I'm just relating my experience.
My mum was from Torquay and moved to Wales after marrying my dad. What she encountered in his home village was awful. She wasn't accepted for not being Welsh, let alone not speaking it.
I was thrown together with a girl who became my best friend as she couldn't speak English and had to at some point, even though she went to a Welsh medium school. I picked a lot up from her, but we drifted apart at secondary school.
I carried on learning Welsh as I enjoyed it and had a wonderful teacher, so went as far as A level with it.
And yet, I still wasn't accepted in my own local community as despite trying endlessly, I was ridiculed for not being Welsh enough - I was even called "half-caste" by some (I'm white). People would pretend they couldn't understand me when I spoke Welsh to them.
It was very hurtful and now I'm flung back to those days whenever I walk into the pub and given the side-eye accompanied by an insult in Welsh. I find small communities like mine to be cliquey - something I've never come across in large towns where English is almost exclusively spoken.
Some of what I wrote about "Welsh Not" was printed as part of a piece about Welsh history in a local paper but the first thing a local farmer announced to his friends in the pub I waitressed at was that I was the girl who "tries too hard to be one of us, but she never will be, will she boys" (in Welsh).
I've never come across racism (that's what it feels like to me) in other places, and I've lived here on and off for years. I'm fluent in French and passable in Spanish, yet people I've mixed with in these countries haven't treated me like that. Most will switch to English, even if they're limited, in an effort to make strangers feel welcome.
Maybe if I was more brazen and thick-skinned I'd be able to shake it off, but it still upsets me. It upsets me even more when I get visitors who tell me they come across rudeness like this - though maybe the same people doing it to me just have an axe to grind with me and are rude to people they know I have staying with me.
As for the road markings, I drive abroad, but never see bilingual markings competing for limited space, crammed and abbreviated like I do over here.
