My mother died when I was 6 years old. My grandmother was with me when we were told about her death. I remember feeling sad, though the thought of loss (and its permanency) didn't really affect me negatively.
I guess to make it easier on me, I remember how the rest of my family and relatives would just remind me of how my mom would always be with me, and even personified her as a butterfly.
To this day (I'm in my early 30s), every time I see a butterfly, I'd still think of my mom and it puts a smile on my face.
