nagnanimous
Nagnanimous is when a person who’s always on your case decides to leave you alone for once, probably because they’re too lazy to argue.
My sister didn’t make me do her homework. She just said, 'I’ll fail anyway.'
My mom didn’t yell at me for leaving my shoes by the door. She just said, 'I’m too tired to care.'
My dad didn’t shout at me for eating ice cream for breakfast. He just said, 'I’m too full to fight.'
