 a man behind bars

we only see his face and his hands

he is holding the bars

he looks sad, he has red-rimmed eyes

he has not shaved

he wears a black and white striped hat and t-shirt

because he wears a prisoner outfit and he is behind bars, we can deduce that he is a prisoner

because he has red-rimmed eyes -> he may be sad, regretful or exhausted

he is looking at us as if he were expecting us to help him 
 this picture represents a prisoner in his cell
he looks like he'd rather be outside

Structure en if -> voir le conditionnel
