yesterday i had to do an english assessment for a school. There was a task where i didn't know which tense i have to use.
the phrase was:
when i was in Germany i ... ( see ) marc very often because we ... ( work ) in the same building.
I think it's the past simple, but it confuses me because we talk about actions which happened in a period of time in the past, so thats why i think it could be the past continues as well.
What do you think?
Sorry for the mistakes

Thanks
Andrin
