"...and when she laughed her grey-green eyes sparkled with disappointed shyness and the tip of her nose nearly met the tip of her chin."
This quote was a striking example to me of how really simple details can evoke a lot of emotion. It really makes a case for showing and not telling. Joyce doesn't tell you exactly what she feels; instead he very precisely describes her facial expression. While there is a little bit of subjectiveness in describing the "disappointed shyness," you never get a direct statement about how Maria's trying to hide her emotions. I think the best pathos comes when the author doesn't tell you how to feel but instead gives you the images for you to judge for yourself.
