what i find funny is that the noise it makes was originally a teen deterrant noise. sort of used for like crowd control. i guess if you hear that tone after like a minute it would get annoying and i would leave the crowd. personally i think it's rather stupid. and I agree, kids need to put their phones away and pay attention. my friend is ALWAYS texting in class, then when it comes to tests and stuff he asks me for help. i don't know what's worse, the mosquito ringer, or the clicks of texting
