There are no masks at 4 in the morning, it is impossible to conceal yourself under such insomnia, such tire, or such intoxication.
This is why we leave our beds where the demons stay to go to house parties where the 'normal people' play. Because the masks begin to suffocate your face and you'd give anything for anyone to see just a trace of honesty in your life built of formalities and lies.
The drinks set in, the feet lose traction, children groping blindly for meaningless interaction.
