How people who don't have siblings think siblings greet each other:

"Hey."
"Hey"

How we actually great each other:

"helloooo"
"gET OUT OF MY ROOM"
_____________________________

"Can you-"
"No. Go away."
______________________________

*does something*
"Stop."
______________________________

"*screams sibling's full name*"
*runs*
______________________________

"I hate you"
"Love you too"
______________________________

"Will you stop"
*mockingly*"Will you stoppp"
