Nick name is an informal name for someone or something, especially a name which you are called by your friends or family, usually based on your proper name or your character (Cambridge Advanced Dictionary). I have had at least 6 nicknames with their own story. My first nickname is 'Em bé' (Little Girl). My parents used to call me like that because I am their youngest child, even when I was a student. My brothers and sisters called me 'Tũn' (meaning something like small but ugly name). I knew, they called me by that name because they wanted to tease me and it implied that they loved me. That name was still used even when I had nieces. I remember my first brother-in-law called me Aunt Tũn on be half of his children. And at school, I was the monitor of my class from Grade 1 to Grade 8, my classmates called 'Lop truong' (Monitor). They hardly ever call me by my name. My fourth nickname is 'Quyên Tàu' (Chinese Quyen). It was created by a neighbor. She is about 8 years older than me. Maybe my name sounds Chinese and my hair looks Chinese. :-). At work, I am named 'Quyen 2', so that I can be distinguished with Quyen 1, Quyen 3 and Quyen 4. We have 4 teachers called Quyen in my department. So interesting that this name is rare but it is one of the most popular name in my department. Once I made a joke of the name Quyen 2 with my friend. I said number 2 made me always a number 2 person. So sad. I also know that in someone's contact, I am named '1 call'. Now I am number 1. :-). Happy.
I love my nicknames. They go along with my life and they remind me of my childhood and people who surrounded and surround me now.
