When the headmistresses commented on what a foolish girl Mary is, that essentially summed up the plot. I wanted to like Mary but they've built this character such that her actions only served to push the plot in a way, but every move she made was inconsiderate and well, foolish. When you get to a strange place, instead of being careful you just bloat up from some stranger's praise? And leave them information about you (or in this case, people close to you)? Also at the end when they fly home on the fixed broomstick---neither of them had any magic left and Mary never used the last flower and throws it away so how were they able to power the broomstick? Makes no sense.
