I got that experience when innocent me was holidaying in the US. My friend a recent resident in the US who had settled there from India hushed me down when I loudly told her I wanted to buy prunes. We had just got down her car and were walking towards a Mall.
I love prunes and little did I know then that Americans eat them when they get constipated. So the conversation that includes the word prune is totally banned in the US is what my newly Americanised friend told me
I obeyed and never uttered that word until I returned to India.
Do you think prunes is a bad word?
