In my new fic, Professor McGonagall arrives at Hogwarts during the middle of August. I want to know what you think- is it feasible that teachers would arrive that early? Also, what do you think that Hogwarts is like during the summer? Is it totally empty, or do some people stay all year? What do portraits/statues/house-elves/etc. do when the students are gone?

I'd really love some help with this! Thanks.
