When leaving a job under good circumstances, even though you didn't want to leave, would you do tiny acts of defiance anyway?

I got a wonderful temp position, as a receptionist, at a wonderful factory where they make precision tools for the aerospace industry. I was replacing a gal who was out on maternity leave.
Of course, I was very over qualified for the job, and there just wasn’t much to do except keep an eye on the coffee and field and transfer phone calls. But I loved everyone I worked with, and the factory itself just fascinated me.
The gal who I replaced came back part time for most of December, and we became friends.
Last Friday was my last day, though. However, they will be looking to hire another person to work the office, and all but promised me the job if they get the go ahead, so I’ll just have my fingers crossed.
So…I didn’t want to go. To make my sadness known I fucked up the date stamp we use to stamp invoices, and I taped one of her drawers closed with one strip of clear Scotch tape (not the heavy duty stuff.) It’ll be easy enough to actually open, but the date stamp….Lord that thing gave me fits! I almost got the hang of it before I left, and maybe she knows some secret to it that I don’t know, but changing the dates was a matter of trial and error, stamping and stamping until I had it right. If I came back to this I’d faint!!

So is this something you might do, if you knew your audience well?
