She couldn't remember when his bright, hopeful eyes began to turn into burnt-out flashes. Or when his silk-like hair became the dry clumps of strands that it now is. Or when his charismatic character became a crazed one. She couldn't remember how, she couldn't remember when.
What she does remember is the night that he had completely broken down in front of her.
She hates herself for not noticing his brokenness any sooner. She noticed the way he didn't call to check-up on her anymore, she noticed how he barely even visited her now, and she even noticed how he would not look at her face whenever they would cross paths in the corridor. She noticed the way he was gradually drifting from her, but she didn't notice the fact that he was drifting from his self. She hates herself for only noticing what he stopped doing with or for her, but not what he stopped doing for himself.
She was too selfish. Too selfish to notice the voice that he was gradually losing everytime he had to speak in class. Too selfish to see that the dark circles around his eyes were growing bigger and bigger everyday. Too selfish to notice his thinning body. Too selfish Too selfish to even see the scars that ran down his arms.
She was too busy thinking for herself, that not once did she even think of him. All the while knowing that all he did was think of her.
