I really sorry
When someone tries to apologize but their brain short-circuited and they just said 'I really sorry' instead of 'I’m really sorry' and nobody knows why
'I really sorry I called you a chicken.', said by a kid who got into a fight over chicken nuggets
'I really sorry I told your crush you were ugly.', from the kid who also told your crush you had bad hair
'I really sorry I made your mom cry.', from the kid who also made your dad cry
