One day during the time I was working in another state in India (Each state in India speaks different language.Hindi and English are official languages.If you know these two you can live anywhere) I was in a share cab returning home after work. It was already packed with 3 people and I had to squeeze on one side. To my surprise this people were also from my state and were very busy chitchatting in my mother tongue. They thought I was a native. One of the girl noticed how squeezed I was between them and tells the other to adjust a bit. Then this other girl very rudely replies 'Oh thats enough for her.Look how skinny she is' I just thought of replying back and giving them a surprise but then thought of listening to more of what she had to say. But then they got engrossed in other talks.
Another similar same mother tongue experience was when me and my husband was sitting in a park and I was busy eating an ice cream(He didn't wanted one) so we weren't talking. . Then one of the two girl sitting nearby us tells the other one 'Poor boyfriend.Look how she is eating the ice cream all alone ' I turned to her and replied in our mother tongue that he is my husband and not boyfriend. The girls stood up and left the place. I had the best laugh that day.
