Supervising a bachelor thesis is not an easy task, especially, if you believe in the phrase of 'bad teachers are criminals', if you want to enhance the inquisitiveness of your student, and if you want to motivate one to be in academia. I am happy that I could maintain all these three criteria successfully.
