再也学不会海绵宝宝的笑
[zài yĕ xué bù huì hăi mián băo băo de xiào]
'再也学不会海绵宝宝的笑' can mean ‘unable to learn to laugh like SpongeBob anymore,’ showing that the person might find it hard to smile innocently and happily again. SpongeBob represents simplicity and purity, so not learning it means losing something pure and happy within oneself.
