Actually was just a doodle but I liked the concept so I edited it.
It's little Ron and Ginny, not sure what age, I've lost the ability to judge the age of children correctly...
I've always liked the notion that Ron and Ginny are close siblings. I think that's part of the reason why she mocks him later in the books, after she turns into Mary-sue Weasley. I like to believe she is a little jealous of Hermione and Harry and upset at the fact that Ron doesn't seem to need her as a friend anymore... but that's just my interpretation.
Adorable
I did always view Ron and Ginny as very close siblings as well, them being the two youngest. Interesting interpretation~
