Sharon and Sirius hosted "Ask a purebred anything Magical’ seminar while Evans and Potter went on their date.  Reggie was disillusioned near enough to watch the chaos and it was entertaining chaos.  He had to admit to being amused.  And appalled at the ignorance of some of the questions.  Yes, more than just the red-headed muggleborns attended, but they were safe and in public.  The seminar was so popular and fun that groups of muggleborns were talking about it for days afterward.
