What really happened on the EVER GIVEN

"I am not ‘politicizing the issue’ — I simply asked you to pick up your room!"

"He just talked me into giving him a 200% raise in his allowance. At least we don't have to worry about him not succeeding in business when he grows up."

"Just sign it, or I'll post YOUR old report cards on social media."

"This is the little league. You can't negotiate a signing bonus"

'Baby sand shark eat their siblings.'

'Only two cookies? What is this -- a quota system?'

'He's bitten me for the last time!'

"It's hard to believe the adults think he's so lovable!"

'I don't care whether you think it's an affront to your 'Human Rights', I still want you to go to the naughty corner!'

"You already have one of each. With whom are you dissatisfied?"
