>>2274648For your reference, here's what "ditz" means in the eyes of both the official dictionary and urban dictionary. Again, whatever your intention, this is what you're calling Lilly when you say she acts "ditzy," and getting frustrated when other people are offended is only ignoring your own mistake.
I recommend calling her cute and playful behavior just that - cute and playful. There's no better way to describe it and her heart-melting effects.
