A smile reflects self satisfaction and a kind of inner peice...I smile wen some old memories of childhood , of frnds or clumzy actions come to my mind;
I smile wen i c ppl in love (couples) of watever age they r especially the old ones.
I smile when i c cute kids, playing with inossence thinking that life is so easy and cheerful
I smile wen i look into my folks, brothers and sis eyes and know they are beside me mind and heart.
I smile wen i succeed reaching a goal,
I smile when i wake up in the morning
I smile wen i look into my self in the mirror as well ;) ;)
I hope all ur lives would be full of smiles :D

Gd luck !
