You arrive at the office in the morning, turn on your computer and while it boots you grab your mug and head to the office corner where you store Nescafe, Coffemate and sugar. You fill in the ingredients of your favorite cup of coffee, put some water in the kettle and heat it up. You then take the kettle back to your desk only to find that there's no mug.

You're really surprised ... who could have dared to touch stuff on your desk let alone take something out?

You begin to make up scenarios in which this could have happened; have you been acting extra nice to people at work so that perhaps one of them thought it was Ok to borrow your mug? did the cleaner think it was junk and threw it away? or is someone in the office trying to play some sick joke?

You panic and decide to take a look around the office to see if your precious mug lies on someone's desk or worse in some bin. Your colleagues notice you going around and ask what's going on. You tell them your mug is missing. They ask when was the last time you used it. You say you've seen it  only YESTERDAY and you stayed at the office till 1am last night and was the last to leave, which means that whoever took it did it overnight.

You keep looking around till you come back to the same office corner where you store your Nescafe ... the same spot where you left your mug exactly 10 minutes ago.
