No smears

Today I worked from home. This has its advantages (no journey), but I also discovered a disadvantage.



I was busy working, computer was running, cup of tea. The sun was shining outside, right through my window. My living room was beautifully illuminated. But what was that..? I had washed that window this very weekend...

[ or so I thought... ]

Grr, I thought I did a good job...

You can only see those smears in that particular light. If I had been working in the office, I would still believe I was a good window cleaner...
