Памагите, help me, օգնեցեք​

When my parents were coming back, we had a party

When I was opened a door, they danced in the dark

I found this girl's phone number while I was cleaning your room

While we were waiting, we started to write the invitation

I taught a gym class when I was hearing about the plane crash

Someone called you on your mobile while you were taking the dog for a walk
