H is not always silent

When I was in school, I used to ask a lot of questions….!!

One Day I asked Ms. Doris, our English teacher:”
Why do we ignore some letters in pronunciation? eg. The letter….’H’…….in Hour, Honest, Honor….. e.t.c………???”

Ms. Doris: “We are not ignoring them; they are considered silent.” …!!
(I was even more confused……..??)

During the lunch break, MS. Doris gave me her packed lunch & asked me to heat it in the cafeteria.

I ate all the food and returned her an empty container….!!

Ms. Doris:—- “What happened, I told you to go and HEAT my food & you are returning me an empty container??”

Me: — “Madam, I thought ‘H’ was silent”
