The voices of my little son and daughter are the most wonderful songs that I ever heard... and I know perfectly that in several years (months minutes, seconds... this is life, is the same) I won't hear it again... I'm not dying... they're growing (so, a little part of me is dying).
I'll really miss that song, the perfect song of their laughs with that voice...
For now, I'll continue enjoying it, and I'll record it, in my smartphone, in my mind... and one day, in a dark night, I'll bring back that perfect song, and I'll laugh with them...
Like life itself.
