**Prompt: trapdoor **
Everybody needs a trapdoor:
A trap to get a prey
And a door to leave with the prey
Don't let your door become a trap
Trapping preys and dumping them dead
A trapdoor: a prey and the predator
Your guess is as good as mine!
A trapdoor for locomotives and birds in their nests
Alight freely with it or hide your booties down there
Whichever way you apply it; gives a result desired.
A trapdoor for theatres
For quick bursting onto the stage and exit
Become a performing artist and enjoy the show
A trapdoor: a necessity for all mortals
Either in the positive or in the negative
All mortals shall pass through
Get a trap and don't leave the door behind.
