This has always been something I have loved. It explains that what we speak isn't what our mind often thinks.

BOY: He says he saw her today. He doesn't tell her that it's been forever since he's seen her. He doesn't tell her that she looks even better than before. I see a typo in the next line though. It should read I asked her how she was doing. He needed to tell her that he'd pick her over any girly he's with. But instead he just uttered the words i miss you. I miss you are the words that replay over and over on repeat in a girls mind. Trust me I would know. He should have told her he loved her but he didn't. He hugged her and held her for the last time, and went home and cried like a baby.  He lost her, but in all reality in the end it's his fault he lost her.

GIRL:
She saw him today. Instead of asking if she cared, she only wondered. She couldn't stop staring, and asked him about his girlfriend. She assumes he's happy instead of asking. He couldn't look at her, or so she imagines. When he told her he missed her, she didn't believe it. He hugged her, and she went home a cried.

She loves him and he loves her. But neither one of them will ever know because neither one of them can speak their mind.
