Under the weather
Things go wrong
it's going to be a stormy day
I'm sick or unwell
The ball is in your court
it's your time to speak
It's up to you
throw the ball
Spill the beans
You dropped something
unveil a secret
Things didn't go as planned
"Let the cat out of the bag" is the same as...
spill the beans
spill the tea
both are correct
Pull someone’s leg
encourage someone
wish good luck
prank or bad joke
Sat on the fence
undecided
gossip
lazy
Through thick and thin
situation than repeats once and again
being there under any circumstance
Once in a blue moon
something weird
a sad event
something that rarely happens
Take it with a pinch of salt
don't take it seriously
take it seriously
