The Durselys as it turns out, are the most boring human beings on the planet day in and day out they follow the same schedule. Harry's cousin is back home. The school he goes to must let out earlier than Hogwarts which is good, saves me the time of rounding up the livestock as it were, they certainly look the part. Now I could just tear down the wards with wandless magic since whatever Dumbledore put here is, from first glance, laughably underpowered and if it were alive I'd go as far to say malnourished and the Ministry wards are geared for detection rather than defence so they have all the structure of wet tissue paper but I'm not going to do that because that type magic leaves traces that can be followed by powerful people (Dumbledore) and I'd rather not have him on my back spells can be finessed to be untraceable but commanding your raw wandless magic to tear down wards you don't know the content of is not only hilariously idiotic it's reckless and very easily traceable.
