Stages of loss.

1) You see your camera lying around somewhere and think "I'll take that with me on the weekend".
2) The next day you pack for the weekend, and it's apparently not lying around somewhere.
3) You spend a few days waiting for it to turn up, because maybe it's lying around somewhere under something or behind some stuff.
4) You start randomly looking under stuff on obvious horizontal surfaces where things might lie around.
5) By this point it is the next weekend. You tidy up significantly, because if it is lying around it won't escape exposure if you tidy up all the way down to the surface of the furniture.

It's still lost, so I'm currently at this stage. My plan going forward is:

6) You wait a few more days or a week, because you need to build up strength and give it another chance to be found accidentally.
7) You look behind heavy furniture.

You buy a replacement. Lucky always buy cheapest camera.
