you wondered where your marbles went.
I did, one day trying to get rid of some letters, lazy me, not getting the shredder out of the cupboard, so put them in a bucket, set light, which then proceeded to set light to the plastic bucket, oh dear, which almost set the place on fire. You do anything that makes you think, now why did i do that....
I made my boss some coffee in a coffee machine and forgot to add the water. He lifted the top off when he smelt a funny smell and hot coffee grounds flew out all over his linen suit. Funny really - he was so particular about his appearance and so vain.
I once burned a letter (from an ex) in a plastic bathroom sink (rented property), obviously the sink melted and I had to confess to the landlord and pay for a new sink.
Oh and I made someone a cup of coffee at my sons house (a man who had come to measure the windows) - only it wasn't coffee it was Bisto Best Onion Gravy granuals and I added milk and sugar. He drunk some of it before he mentioned that he thought I had given him soup.
the kitchen drawer trick is a good one, it sticks, pull hard, out if comes, all the contents on the floor, not a good look either scrambling around on the kitchen tiles.
My ex (after a "disagreement" when he insisted you needed to add flour to instant gravy as his mum used flour in her - obviously homemade - gravy) once confessed to being rather puzzled as to why his fishfingers weren't cooking until it dawned on him that he was using lime cordial instead of oil!
Last week I was about to enjoy a cup of tea at my sister's house when my BIL suddenly dropped a book of 11 1st class stamps into it. He's partially sighted and thought it was the vase he stores them in. Had to be the 1st class ones too didn't it?
