kurt: he's never been the happiest person, but it gets worse when he's sad. you aren't always at the house when he's sad so he just cries until you get home to comfort him. you and kurt hop in the bathtub together while you rub his head hearing his choked back sobs against your chest. it always breaks your heart seeing him cry, but he just cries to cry or he's feeling depressed.
dave: he's almost never sad, but when he is he's numb. he doesn't want to upset you by letting you see him cry, so he hides it all. but you always catch him crying. he tries pushing you away cause he doesn't want to come off as weak, but you'll never leave him. you and dave eat ice cream together and cartoons while you hold him close to your chest
krist: krist only cries during super sad movies or something traumatizing happened, but he never tries to hide his sadness. you often read to him to help calm him down, or you kiss his face all over till he falls asleep or stops crying.
