Flash fiction

The flash fiction I found was titled "ghost Bike" by Thomas Cooper. It's about a guy working on his bike in the garage while his wife is upstairs in the bedroom. After he finishes the bike he stumbles up stairs because it would have been time to put his Daughter to sleep. Once his wife see's the paint in his hands she gets dressed and they head to a diner. I get a sence that he has lost his daughter or his whole family in some accident. Maybe he is just imagining his wife. This story just seems dark to me.
