She wouldn't have remembered if she hadn't happened to chance upon the headline in the Daily Prophet that morning.
Wizards and Muggles Alike Celebrate Mother's Day With Festivities, it said, in big, bold letters. Her hand paused over it just as she was going to pick it up.
She had never believed in the originally-Muggle tradition of Mother's Day. It was just another pointless reason to spend money on useless gifts. And to spend time with her son, a voice at the back of her mind added. She frowned.
It's true, isn't it? the traitorous inner voice continued. When have you ever bothered to properly speak to him? Learn about him? Be a mother, to your own son?"
She sighed. It was always terrible when pangs of conscience came back to bite her. It was not an occurrence that happened often, but clearly, today was not her lucky day.
"Well," she muttered, "There's only one way to fix this."
She got up from her chair and began to head to the door. Then, she suddenly paused again. A gift, surely, was in order? She had to bring something with her to convince her son...
She looked around her room, her eye catching on one particular object. She smiled.
She knocked on the door hesitantly. If she knew her son, she had a feeling he was not going to be please. He would be justified, that annoying little voice told her, as she winced slightly at the unpleasant truth. As she waited, she looked around the little garden in front of the house. It was rather pretty, she thought. Some weeds had started to grow on it, however. She frowned.
The sound of the door opening broke her train of thought. To her surprise, it was Parvati who was standing in the open doorway. Clearly, the latter was shocked to see her too.
"Mrs Zabini?" Parvati stammered. She nodded in response, pushing a strand of silver hair behind her ear.
"May I come in?" she asked, her mind nowhere near as calm as her voice would imply. Parvati hesitated, then nodded and stood aside to let her enter.
Blaise, who was sitting on the living room couch rather contentedly, immediately stiffened when she entered. "What do you want?" he asked, curtly, even as he stood up.
Mrs Zabini sighed and then decided she might as well cut to the chase. From one of the many folds in her pocket, she took out a little flag and waved it. Parvati stared at it for a moment and then burst out giggling. Blaise frowned. "A flag of truce and a bag of galleons? Really? We are not at war, mother."
She raised and eyebrow at that.
"Well, even if we were, a simple flag and some of your money wouldn't fix all these years! You have killed men for your personal gain! And you never cared about me!" There were tears in Blaise's eyes as his emotions spilled over.
She sighed. "The men I killed...Well, all I can say is dad men don't bite." Parvati gave another little giggle at this as Mrs Zabini continued. "And for all these years...I'm truly sorry. Which is why I'm here now. To spend all the time in the world time with you, my son and my daughter-in-law -" Her voice was cut off by a baby's scream coming from one of the rooms inside. Parvati immediately ran inside and soon came out with a child in her arms.
"And my granddaughter, evidently," Mrs Zabini finished, a small smile playing around her lips. Blaise looked at her suspicously for a few moments, then suddenly smiled as well. "Welcome to the family, mum."
