I was at school when it happened.
You were there for the first time.
He was with Pilar at the train station.
She was sure that she will go to Rome next summer.
We were so young then.
You were so sad during the ceremony.
They were excited about going to New York.

Was I there with you?
Were you at the party last night?
Was he sick last week?
Were we late for the show?
Were you at the time?
Were they dressed appropriate?

I wasn´t there with him.
You weren´t there for me when I needed you so badly.
He wasn´t really sure about it.
We weren´t late fortunately.
You were so happy to win.
They were extremely motivated to join the spanish classes.
