In books, promises always make me cry, because they're broken...

(Not mine, Rick Riordan and James Dashner's)
Example #1:

Thomas: "Listen to me, Chuck. I'm sure you have parents, I know it. Sounds terrible, but I bet your mom is sitting in your room, right now, holding your pillow, looking out at the world that stole you from her. And yeah, I bet she's crying. Hard. Puffy-eyed, snotty-nosed crying the real deal."

Thomas: "Don't give up, Chuck. We're gonna solve this thing, get out of here. I'm a Runner now-I promise on my life I'll get you back to that room of yours. Make your mom quit crying."

Chuck: "Hope you're right,"

Thomas: "I swear, Chuck, I swear I'll get you back home."
Can we all cry now? Go ahead *hands everyone a tissue box*

Example #2:

Nico: "you're planning to go anyway, aren't you?"

Percy: "Yeah, I have to find Annabeth. I have to help, even if they don't want me to."

Nico: "I won't tell on you, But you have to promise to keep my sister safe."

Percy: "I...that's a big thing to promise, Nico, on a trip like this. Besides, she's got Zoë, Grover, and Thalia-"

Nico: "Promise,"

Percy: "I'll do my best. I promise that."

Nico: "Get going then! Good luck!"
Warning: we are almost out if tissues! I repeat, Warning: we are almost out of tissues!
Warning: imminent danger of a tears flash flood!
