Let's csi all over the Tim card's ass

Alright, who did it?

Who bought a $10 gift card for Tim Horton's coffee shop and stuck it under the windshield wiper of my Jeep?

Somebody did, because there it was. With my name on the outside and no giver's name on the inside. But nobody's telling. I asked everyone at work. I've bugged Dave until he's mad at me. I've asked my family and friend(s). Nobody's fessing up.

This could very well be the Enduring Mystery of My Life. (That, and who gave me the floral patterned china coaster set for a wedding present, because the card fell off and I don't know... but they're lovely! Thank you! Whoever you are!)

Mysteries drive me nuts. In fact, my boss suggested that somebody spent that ten dollars exceedingly well in the drive-Cathy-nuts department.

Let's examine the facts as I know them:

Friday afternoon, about 3:30 p.m., Dave showed up at my office with four coffees from Tim Horton's. He often brings in coffee for the girls I work with because he knows how to treat a woman and realizes it's always in his best interest to be nice to us.

Friday night I finished work about 4:50 p.m. after an exceedingly long short week (the short weeks are always the longest because you do just as much damn work, only in a shorter period of time). I went to the parking lot, which is directly behind our building, got in my Jeep and drove home. I pulled into the driveway and Dave was already there, busily doing yard work.

"What's that?" he said, from across the yard.

"What's what?" sez I.

"On the windshield. There's something under the windshield wiper."

"Huh," sez I, and walked around to the front of the vehicle to look. A Tim's gift card sat under the wiper blades. I had driven all the way home and not even noticed. But Dave noticed, from across the yard.

It said "Cathy W" on the outside, in round almost-fancy letters. It looked a lot like Dave's writing. I tried to thank him but he wouldn't have any part of it. In fact, he started to get angry at me for insisting it was him. Now, he almost never gets angry at me, even though I may deserve it. And he can't keep a secret worth beans. I don't know how many times I've inadvertently ruined a surprise because he couldn't keep a goofy grin off his face. But he wasn't grinning as he vehemently denied giving me the card.

"Huh," sez I. Because I am a master conversationalist.

I then proceeded to ask everybody I knew. I even posted it on Facebook. Nobody claimed responsibility.

I was like, feck, even roadside bomber bad guys claim responsibility – why won't anybody admit to giving me a card for free coffee?

So I'm asking. One more time.

Who gave me the Tim's card????????
