Seeing the same student on her phone for the umpteenth time that period, the frustrated teacher told her student to put the finger-crack away and try, for the sake of all that is good, to control her addiction for the final five minutes of the period. Jonesing for another TikTok fix, the girl managed to pocket the device for all of 17 seconds.
