Feelings
I have butterflies in my stomach
Nervous, anxious,
Piece of cake
really easy
head in the clouds
to be unware of what is going on/not paying attention
I feel like a fish out of water
to feel uncomortable
time flies
Time went by really quickly
hold your horses
wait, be patient
I'm on cloud nine
to be very happy
raining cats and dogs
raining really hard
All in the same boat
Have the same problem/ be in the same situation as someone else
I got cold feet
become too scared to do something
sick as a dog
to be very sick
open a can of worms
get into some messy or complicated
to be upset about something that happened in the past that can't be undone
two peas in a pod
to be very similar
let the cat out of the bag
to let the secret out
