One of my most はずかしい moment

A few years back when I went to visit my family in Colombia. I was walking with a few of friends and family, we encountered this lady asked my grandmother for her name because she happened to recognize her after that then she told us who she was. She was old kindergarten teacher from when I was younger. After that she starts telling embarrassing stories of how a disruptive student I was and how out of all her students she still remembers me one of her most interesting students.
