A knock at the window

Today's discovery was that the foam letters that stick on to the side of the bath also work well for adding lettering to steamed-up windows. The smallest member of the household helped with the wording - this was the start of a knock knock joke although the punchline was never revealed...

"..window who?"

"..window you think you'll work out the punchline?"

It wasn't that either. I like the effect though, and with the long dark months offering many days of steamed-up windows and sometimes not a great deal else I may well return to this idea yet..
