Here's the paragraph:
I worked in the bank for a specific period of time in the past. One day my wife and I knew each other. Of course, that day was during or within that period of time.
Can I simply say this sentence to give the same meaning?
I was working in the bank when I met my wife.
I know that continuous tenses express a specific period of time (ex: working for an hour or a couple of hours continuously and without interruption or stopping). Can they express that I worked in the bank for months or years as I did in that sentence? Is using the past tense after "When" gives the same meaning of "One day"?
