I am a Welsh MSc student studying at a Welsh uni. One time in class a fellow student announced to the whole class that I sounded ‘really really Welshy’ and that she ‘had a dream where I was standing at the front of the class giving a lecture sounding really Welshy’.
The student seemed very amused when telling the class this. I felt uncomfortable at what she said. I could not imagine announcing to a whole class of students, for example, how really really African one of the students sounded! Especially if I was in Africa!
This later led to me (along with other factors not related to uni life) writing a withdrawal letter.
