I disliked history classes at my high school in Newcastle upon Tyne, England.
The focus on studying for examinations did not fit my learning style. The teaching style often reflected the teacher's lack of interest in teaching.
To be fair, I did not then have the life experiences to sufficiently understand the nuances of how the world works.
Then, one day my ears pricked up when I heard the teacher talking about exploding mail boxes and post offices.
We had reached the Ireland of 1916. Domestic terrorism seemed so improbable.
