Haven't done exactly that with keys, but similar. Latest favorite self-idiocy: call someone, and then mid chat, go into a panic, because I can't figure out where I left my cell.

You may laugh, hihi. It is rather daft

I've driven all the way to work before realizing it was my day off.

I've handed in a homework report after working all weekend on it to be told I handed in my report last Friday after free period.

Can't count the number of times I forgot to pull up my zipper.

I got up for school one Sunday evening at 6:30 after an afternoon nap.

I've landed on the floor after changing around the furniture in my living room.

Too many times I have came back from swimming with my shirt inside out.

Got $40 cash back at the self-checkout at Walmart and forgot to grab it.
Went back in thinking it was still there.

Tried to get back with my X once.

Packed for a family picnic and forgot plates and utensils.

Went on a weekend camping trip and forgot my sleeping bag was in the dry cleaners.

Can't count the number of times I've said "Thank You" when I had nothing to be thankful about. (DMV, Paying a traffic ticket, Being reprimanded at work)

I've ran into a few sliding glass doors.

I've fell 'up' the stairs.

I once set down a box of books on a cat.

I've gotten dressed, hat and coat, grabbed the leash and took the dog for a walk and forgot the dog.

I placed pop 'n' fresh rolls too close to the crockpot and they exploded all over the room.

I heated a piece of 1/2 inch steel to cherry red with a rosebud torch. Shut off and sat down the torch, took off my welder's gloves, went to my toolbox and checked the bracket bend angles, came back and picked up the metal with my bare hand.

Joined Mingle2 thinking I could find someone local.
