Cats and dogs
lighten up
to relax
To Be All Smiles
look very cheerful and pleased after being in a bad mood
burst into tears
start to cry
Speak of the devil
talking about the person that just came
Dissolve into tears
Cry a lot
to see red
really angry
Raining cats and dogs
Raining really hard
Lose your temper
Become very angry
keep a straight face
not laughing when something is suppose to be serious and you think it is funny
Wrap your head around something
to fully understand something
Was on pins and needles
Nervous and worried
bare your soul
Tell someone everything about you
