A couple writing exercises involving windows
Sitting at a traffic light, witness an event involving pedestrians crossing the street. Dramatic like a stabbing, or subtle like a couple walking together, and slowly one pulls their hand away and starts walking a little aside. Or a traffic accident. You pick something.
In a window you can see from your bed, you notice a spiderweb appearing between the panes, but never see the spider.
While vacuuming, a housewife (and mother of 2, lets say) sees a pair of squirrels doing something. Be it the nasty, fighting tooth and nail over an acorn, something, that works as a metaphor for something big in her life at the moment.
On a walk you see a car’s window smashed and the stereo removed from it… jump off from there.
