Why do all the characters house a have a name?

For these maybe:
1. Apparition (thinking about the place)
2. Floo network
3. To say, "we're going to burrow". I hope you understand this.
I can't think of any other reasons right now but i'll comment if i find more. :)

so no one will say that that's their house :))

It probably helps with transportation.

Also, currently saying "the Weasley home" could take you to the Burrow or Shell Cottage. sa pamamagitan ng the time of the epilogue there'd be six different Weasley homes.

because it will be weird if herminoe says to her mum "hi mum, can i go to rons house today?" and she says "yes what is the adress?" hermine will be like "um... i... its called... the weaslys house?" and to make it madami realistic and easier to talk about say if for harry hes lived in 2 places: godrics hollow, privet drive n# 4 so it makes it clearer than harry potters house.
