you were there
Si tu étais là, il pourrait se permettre de prendre des congés.
If you were here, he could afford to take some time off.
— Crazy Rich Asians (2018)
Thank God you were there.
Tu étais là quand c'est arrivé ?
Were you there when it happened?
I knew you were there.
Si j'avais su que tu étais là, je ne serais pas venue.
If I had known you were there, I wouldn't have come.
I was told you were here.
