Analiese racked her brain for an answer to the second question. "Professor, you would need a word. Such as... a name. For example, you can use all the consonants in someone's name to calculate their social number." Was that good enough? She ran her fingers through her hair and started drawing a centaur in her journal. While still paying attention, of course. She wasn't the kind who got in trouble for not focusing.
Analiese looked up and realized that after she had entered Hogwarts, her 'mind reading' didn't work. It probably had some spell or something, that made muggle methods of mind reading not work. Well, that was good. She wasn't invading anyone's privacy.
