When Push Comes To Punch

I think she meant when push comes to shove.

Fig. when things get a little pressed; when the situation gets more active or intense.

The apple doesn't live far from the tree.

I think she meant "The apple doesn't fall far from the tree."

Refers to a father/mother and son/daughter not being different from one another or being identical in their actions, behaviors, etc.

Dad gets caught stealing in his teen years and then his son gets caught stealing as a teen.

The mother might look at the father and say, "The apple doesn't fall far from the tree."

She was stabbing in the dark for a reason

I think she meant:​

"Taking a stab in the dark​" meaning making a complete guess.

Um, that'd be okay. 

I think she meant 'You're in the dog house.'

I think she meant crocodile tears...or perhaps unicorn tears.

Crocodile Tears

Noun Tears that are insincere.

Unicorn Tears

A magical potion that does absolutely nothing, but is sought after nonetheless by suckers who never figured out that the Easter Bunny isn't real.

Blow me over with a feather

I think she meant "Well knock me over with a feather".
