this smile is a timid grin a sad smile a “don’t lose hope” smile, the innocent raise of the child’s cheeks; a closed mouth smile with no teeth inside. this smile is an excited smile free to convey the ups of the day. the “just turn your head a little to the left” picture day smile; the natural, unforced smile of greeting an old friend like no time has passed, the gentle smile while resting your head on a lover’s shoulder, with their returning smile more coveted than your own.
