The woman at the carrot cake stall at 'my' coffeeshop last night made me a very happy person.
When my food was ready, she said: "来，妹妹，你的." *
I haven't been called a 妹妹 for the longest time. Needless to say, I was walking away with a smile on my face. The carrot cake tasted extra delicious.
*妹妹- younger sister... a term you use if you don't know that person well and she seems to be younger than you. Like using the term uncle or auntie.
