Dear Queenie,
Someone I know speaks with an accent and when I asked where they came from they got upset and refused to answer.
Queenie, did I do something wrong?—Etty Ket
Dear Etty Ket,
Possibly the person is self-conscious about the way they speak your language, or they may have had problems where they came from or been discriminated against because of their origins. If they are still upset about your question, you can apologise for upsetting them and do not bring the subject up again.
