The mask hides

frowning

pouting

smiling

yawning

pleading

grinning

beaming

thinking

shushing

smirking

grimacing

lying

 

A face confused

worried

hushed

astonished

flushed

anguished

relieved

unamused

 

Someone anxious

or fearful

or pensive

or sleepy

 

But you can still see tears
