Masked-Out

When you've been wearing your mask for too many hours, and are sweaty, light headed, ready to risk fines or even COVID-19....well, ready to risk anything other that someone else's well being.

After being in meetings all day I am masked-out and just want to rip this off my face! I would rather stay socially distanced at home alone than have to wear this one more minute.
