Eris blushed, she had never been told "thank you" by a hat, pureblood lifestyle or not. This was indeed a moment that should remind her to be nicer to the inanimate objects...
As the girl patted her on the hair, her eyes blink for a moment as she let out a small childish laugh. "How did you come across such a hat, miss?" Eris asked with her interest at a high peak. Positive that they were not sold at the pet shop in Diagon Alley.
Eris looked over at the older boy with a bit of concern spread across her boyish face before fading back to a friendly smile as she tapped him on the shoulder.
"Erm...." she began no sure how to break this since he had already eaten some food. "I wouldn't eat any more of it mister...they say the House Elves went on strike...." Eris continued before holding up her own grime covered spoon and greasy fork as evidence.
