Who are we?

I have to ask my students to introduce themselves. Say who they are. Then, I stopped and thought: Who am I? How would I introduce myself? Really, who am I? It's what we, humans, do. Try to discover who we are. We find it much easy to describe who other people are but find it much harder to do the same thing about ourselves. So, who am I?
A mother? Ok, a mother but that can't be all. Although to society that may be a lot. It doesn't define me beyond the fact that I have children. A teacher? Ok, a teacher but although our profession is one of the main things that define us, it's not who I am inside. It's more how other people see me. Being a teacher is what I do during the day and probably bore non-teacher people talking about all the time.
So, if asked to say who I am, I might say I am a woman who has kids, and teaches or at tries to teach others to speak a language and by doing this I guess I show part of who I am. I am someone who immensely enjoys getting to know people and listening to their stories, and also being able to share parts of my own.
I am a dreamer. The type who dreams stories by day and hopes to write them one day. A brain filled with bits of everyday tales that make me smile, cry, think and want to wake up in the morning.
I am an observer of life. That's who I am. That's who I like to be.
