What was hatched a hen must not try to be a rooster
A gift is the key to open the door closed against you
If the dose is nasty, swallow it fast
One hand washes the other, but together they wash the face
Don't try or pretend to be what you're not.
A gift will help breaking the ice, making friends with people
If something is bothersome, do it quickly.
Working as a team lets you do things you cannot do alone.
Regarding the last one, an American told me it meant:
It takes two hands to wash a face even though it only takes one to wash the other.
It seems opposite to yours.
I dunno. I still prefer my interpretation, but it doesn't mean it is right. Teachers will sort it out.
Okay, thank you Francois.
I'd wait to see what is the bottom of this line.
