Molly didn't realise her door had opened until she heard it close, and she spun on the spot. Finding Arthur standing there with his hand over his eyes made her put hers over her mouth. She stifled her laugh and quietly moved to stand near him. She was close enough to disturb the air around him, but not so close that his slight sway would make him touch her.
Slowly, she moved her hand from her mouth, revealing a huge, laughing grin that he couldn't see. She didn't know what he was doing, but she was sure he'd thought something that should make her blush again. He he was so adorable, standing there, not looking. She kissed his cheek then quickly retreated to stand by her wireless again.
Lowering the volume, she started to laugh out loud. "I don't know what you were expecting, Arthur Weasley, but it's safe to look."
