The following more or less scientific theory of girl’s execution logic neither holds in each flat share nor all time in the case it holds.

First some introduction, when I came home there were three clean glasses on the work space and some stuff on the table, a place it doesn’t belong to.

What happened?

First I’m explaining how this state could have been reached.

A part of the dishes from the dishwasher in the cupboard.

Then three cups on the work space.

Pot, bowl and plate on the table.

In the automata language I would say “The state was entered”.

Now I reconstruct the instructions of my flatmates’ program.

First boot sequence:

1. Think.
2. Wait 10 seconds.
3. Think again.
4. Wait 30 seconds.
5. Throw exception: “Out of memory”
6. Reboot …

After successful reboot:

1. Put most of dishes into cupboard.
2. Put the rest (exactly three cups) onto work space.
3. Put dirty dishes on the table.
4. Put other dishes into sink.
5. Take clean dishes out of sink.
6. Put clean dishes into cupboard.
7. Wait 60 seconds.
8. Think.
9. Wait 120 seconds.
10. Think again.
11. If (dish soap bottle is empty AND is empty since three weeks)
        then throw it away
        else keep it
12. Set timer to two weeks to remind me for testing the age of the dish soap bottle.
13. Go into sleep mode …
