As I see it, in my case I believe these resulted from my inexperience as a professor; for sure, if what happened to me had happened to a professor with 20 years of experience, this professor would have known how to put an end, “that is over”, it is not allowed, cease it.
A ver, en mi caso creo que fueron fruto de mi inexperiencia como docente, seguramente si a un docente de 20 años de experiencia le pasa lo que me pasó a mí, sabe poner fin “se acabó” no se puede, lo para.
