Awwww, I made the little Gryffindor angry. You've clearly never read any crime books. The first step after anything is to keep moving on with your life, don't change it just because someone else tried to because then they win. Do you really think that any time something bad happens people just have to pack it up and head home and just wait for results. Ridiculous. But hey, maybe I should keep my good advice for those worth giving it to.
Naive little Gryffindors who think caution serves justice or answers certainly aren't on that list.
