Show Don't Tell

Today in writing we learnt about 'show don't tell'.  Luke had to act out the word 'anxious'.
This is how he showed that he was anxious:
# Hugging himself tightly
# Clenching his jersey/fists
#  He is on his tippy toes pulling away from the activity
#  He is protecting his body and shielding it with his arms
#  Pursed lips
#  Pale
#  Shaking
#  Butterflies in my tummy
#  Sweaty palms
