Please tell me if there are ones that can't be used today.

It's disappointing to see people complaining LEFT AND RIGHT (chaotically), when they're actually SPOON-FED (more than needed).  "Spoon-feed" means to give someone too much help or information that the person does not have to think for himself.  The person who receives the help or information is "spoon-fed," as if he were a baby being fed with a spoon.

I don't want to WAX POETIC (speak in a poetic manner), but the thing I'm talking about has a certain JE NE SAIS QUOI.  "Je ne sais quoi" (from French) is a noun phrase meaning something hard to describe).

I LEFT NO STONE UNTURNED (did everything possible) searching for info for them, but I think now I should GET MY HEAD AROUND THE FACT (accept the fact) that they don't appreciate my help, and I should let them HIT THE BOOKS (study) themselves.

However, there are four guys who can't be TARRED WITH THE SAME BRUSH (can't be put into the same boat with others). Whenever the other students start complaining, they just SIT ON THE FENCE (stay neutral) and TAKE EVERYTHING THEY SAY WITH A PINCH OF SALT.  [Variant:  "take with a grain of salt"]  Those four students make up the SKELETON CREW (the required minimum to operate), so maybe I'll kick the others out, even though that might make us RUN ON FUMES. 

I hope it's a PIECE OF CAKE for native speakers to check this.   It was "as easy as pie"!

P.S. What's in the brackets is for myself.  In American English, these:  (    )  are called parentheses.
Thank you so much.

You can use them all today.
