Where I come from, that would be 'tree'. I still can't do the English 'th' thing; well, I can, - it's physically possible; but for complex reasons, I just won't ....I do a sort of in between sound; which immediately marks me down as a foreigner. But hey, I sometimes refer, (when speaking to my grandchildren), to perfectly ordinary women, as 'ladies'. Strange, but true.
So I do my best to be understood...within reason. :?

Everyone thinks that their own accent is the correct one. They only really notice their accent and maybe start to feel uncomfortable when they move to a different area.
People have occasionally thought that I can't speak English, even though English is my first language.
Whenever I read posts such as the ones in this forum. Everyone speaks in a Welsh accent in my head.
