Once again today, I realised I would really like to know that Accio summoning charm thing. There are a thousand and one uses for such a spell. The obvious include when the TV remote is just out of reach. A problem if your wand is also just out of reach . Also if you drop your keys on a dark street - why scour the ground on your hands and knees when you can just shout out Accio keys! *
But there are other uses. Wrap it in tissue paper and hold it up to your ear. Accio earwax. Similar use for a blocked nose. Whisper it under your breath and pretend to be a Jedi. The practical joke applications would be endless. Theft would be simple - Accio money.
Are there limits to the spell? If I point it at you and say Accio oxygen or Accio brains will you die? If I point it at a crowd and say Accio hot women who are willing to sleep with me will I score? If I routinely point my wand at exotic plants and say Accio cure for cancer will the necessary molecules jump towards my wand? What about if I aim at a bag of Scrabble pieces - Accio answers to tomorrow's test?
These things probably wouldn't work. There's probably some rule about visualing the thing you want to summon in your mind. But hey, it's magic. Maybe it will work.
The other possibility is that spell that allows you to control people, but using that sends you to gaol. Plus, I would feel guilty turning people into slaves like that - or worse, I wouldn't.
