i am so confused right now , they both look the same to me
as far as i understand past perfect is used to talk about an action that was completed before some point in the past
so :
"i had had breakfast then went to school" looks fine to me
but :
"i had breakfast then went to school" also looks fine to me because the sentence self explains itself because of the "then" placed at the middle of the sentence , the listener can easily notice which action happened first
When should i use Past Simple + Past Simple and when to use Past Perfect + Past Simple ?
thanks in advance.
