The past progressive shows the two actions, both occurred at the same time, but one action began earlier and was in progress when the other action occurred. For
example:
I was riding my motorcycle around the neighbourhood, when it began
to rain.
At eight o‟clock last night, I was working on an English exercise in my book.
Last year at this time, I was attending school.

While I was studying in one room, of our apartment, my roommate
was having a party in the other room.
I was sleeping so tight while my brother was working on his homework.
While she was running down the street to see him, Jun was watching
TV at home.
