"Miss Weasley?" All three kids turned to see Petunia standing there with a comforting smile on her face, "I wouldn’t worry about your mother calling or coming up to harass you. All incoming calls from the Ministry have to go through my office first. I’ve already had to remind your mother twice since the start of the school year that unless it’s a matter of national security; she is to restrict herself to writing ordinary letters if she wants to voice her misplaced displeasure at where her daughter got sorted. As for her trying to come into the castle, there are now intent-based wards which will reroute anyone to the DMLE’s holding cells if they wish harm upon anyone for any reason, no matter how small."
