When the H is Silent - Class teacher teaches English

When I was in class 7 , I used to ask a lot of questions. .....!
    One day, I asked my English Teacher, "Why do we ignore some letters in pronunciation eg. the letter H .......in Hour, Honour. .....etc. ......
My English Teacher said, " We are not ignoring them;  they're considered silent ".......
       (I was even more confused .....??)
   During the lunch break, my Teacher  gave me her packed lunch and asked me to heat it in the Cafeteria.
   I ate all the food and returned her the empty container. ....!!!!!!!
  My English Teacher : What happened?  I told you to go and HEAT my food, you are returning me an empty container.
   I replied,  "Madam, I thought 'H' was silent. 😛
