Flawless Mask?

There are people in this world who are so hard to read. They can mask their eyes without a problem, play false emotions that distract from the truth, and adjust their body language in a way that no one would be able to tell that something is wrong. But, that costume that they wear is never flawless.

Somebody may have already learned what you feel, and probably care about you to no end…even if they barely know you…I just wish that the person I care about, would finally realize it...

Question of the day:
Do you know somebody who is incredible at hiding their emotions?
Does it hurt you when they are hurt?
