...while
I was reading. ...while you were out.
...while it was raining.
...while she was sleeping.
...while we were talking.
...while they were playing.
...while I was cooking.
...while you are here.
...while it is still early.
...while we were on vacation.
...while I was growing up.
...while you were sleeping last night.
...while we were driving to the beach.
...while she was studying abroad.
...while they were building the house.
...while I was waiting for the bus.
...while you were gone.
...while it was still dark.
...while we were watching the movie.
...while I was cleaning the attic.
