I never had any bomb threats in school, but there was one near one of the supermarkets where I live around 2000 I think.Besides that I don't remember. Some students pulled the alarm during classes twice, though.

I can understand if a teacher want to take away someone's calc for playing games, but that's just ridiculous. Your teacher has some kind of problem with people being smarter than her

MEDEA Alas! this is not now the first time, but oft before, O Creon, hath my reputation injured me and caused sore mischief. Wherefore whoso is wise in his generation ought never to have his children taught to be too clever; for besides the reputation they get for idleness, they purchase bitter odium from the citizens. For if thou shouldst import new learning amongst dullards, thou wilt be thought a useless trifler, void of knowledge; while if thy fame in the city o'ertops that of the pretenders to cunning knowledge, thou wilt win their dislike. I too myself share in this ill-luck. Some think me clever and hate me, others say I am too reserved, and some the very reverse; others find me hard to please and not so very clever after all. Be that as it may, thou dost fear me lest I bring on thee something to mar thy harmony. Fear me not, Creon, my position scarce is such that should seek to quarrel with princes. Why should I, for how hast thou injured me? Thou hast betrothed thy daughter where thy fancy prompted thee. No, 'tis my husband I hate, though I doubt not thou hast acted wisely herein. And now I grudge not thy prosperity; betroth thy child, good luck to thee, but let me abide in this land, for though I have been wronged I will be still and yield to my superiors.
