So, my favorite reason for smiling is "you", meaning, the others. I smile when I think of the people I care and love, and when I am with them. I know that I'm not friend with someone when thinking about that person do not make me smile anymore. Being with my friends makes me happy, smiling is natural, I sort of owe them my smile. My friends but also the members of my family, who are also my friends in a way. I smile for a lot of reasons like thanks to a movie, a dream I made... but this one is really my favorite one because that smile I have in those moments is true and makes my heart smile too.

Dedicated to... Ritona Raito, finally. Because I want you to smile too :)
