Crack of dawn - the other side of the window

Early walk with Bernie and the light was pleasing on the moulin window.  Although we don't live here yet, we've spent a couple of summers sleeping inside these panes.  
Old houses here don't have East/West openings because East /West winds are mind blowing when they want to be.  But this isn't a house, it's an industrial building, so Zéphir's power was  overlooked, hence the window. 
I found it strange therefore, waking up on summer mornings with the rising sun, watching the filigree formed by the plane and chestnut leaves scan the opposite wall of the room. I'd wait for them to be at an appropriate place before getting up.  After all a lie in is a lie in. 
In a months time we will barely see the canal beneath us from this window, but today the chestnut buds are still a little reticent.
