#458: Mystery

He did good work; he hardly ever spoke,
and when he did, he never wasted words.
Few friends, even among the IT nerds.
Three times a day he went outside to smoke.

But now and then he'd laugh--a short, sharp sound
as if some joke had caught him by surprise;
no explanation, no smile in his eyes,
and only when no one else was around.

Then one day he was gone--just didn't show
for work, with neither notice nor goodbye.
His coffee mug still on his desk, a ring
of keys there in the drawer. Beats anything.
At last the boss just shrugged and let it go.
I still don't know what happened to the guy.
