Wonderful! I must say, I myself was reluctant at first to go with the premise, feeling there was squickiness in the professor-student configuration, but as they went on, Minerva and Albus made me feel different.
That sentiment pleased me no end; thank you! I always knew that student/teacher relationships can be a challenge to write in any way other than exploitation-escapism-for-kicks detention!fic, and wanted to see if I could make a believable relationship story on this premise. Of course, some peoples' squick on this front is cast-iron - and I totally respect that - but it's super to hear that you came round to Albus and Minerva's point of view in reading this :-)
Also, very funny and sharp observation of character: "He spoke with the uncanny insightfulness and sense of purpose of the slightly-drunk."
