Just about everyone has pretended to be "asleep" before, but these two twins have mastered the art.
They thought mommy was gone until morning after she put them to bed.
In the video, twins Maya and Keira are seen standing in their cribs interacting with one another.
Unbeknownst to them, mommy was watching the entire time.
When they heard their mom's voice over the baby monitor, they immediately laid down and pretended to be asleep.
