I was on a trip last week.
Mary was in the park half an hour ago.
We were in Bucegi last summer.
They were at the party yesterday.
Were you in town yesterday?
Was Tom there, too?
Were our friends in the mountains, too?
Were they at Ann’s party?
I was not at home.
Tom was not here.
You were not in the mountains.
They were not in town last week.
