Buttons

There are many dangerous buttons
In this world. Some you wear to make
A point, whether humorous or profane
(I got into a fight once over a message
Pinned to the front of my jacket, for example).
Some buttons live on machines,
And are marked with big red letters
Saying things like “Detonate,” or “Launch.”
These buttons do significantly more damage
And are very, very noisy.
But the scariest and most dangerous button
You will ever find – both for you and
Everyone else – is quite modest, and bears
The simple legend: “Reply All.”
