Broken Wings

Victor was standing in the sitting room alone, looking out the window. It was getting dark outside and a butterfly with blue wings was sitting on the window sill.
Close, open, close, open.
It can fly away any second now.
That thought made Victor feel like he was suffocating. He wanted to catch the butterfly and crush it in his hand. He wanted to grow wings and fly away.
"Darling?" He heard Emily's sweet voice calling from the dining room. He realized he was clenching his fists. He smiled, leaving the room. Red nail marks stayed carved into his palms.
