A beloved toy
This is a toy my mom got for winning a school competition when she was 15. It is my oldest toy, I can hardly hold it now because it's so very old, but I spent my childhood with him, and I love him very much. He is 37 years old and remains unnamed.
Biayna (Yerevan, Armenia)
A symbol of freedom
This is a picture of my passport, it is very valuable to me because it is a symbol of my freedom. I can go virtually anywhere with it, and without it I am trapped.
