I have some troubles to correctly express myself in a certain situation so I'd appreciate any advice you can share with me.
Situation: I'm looking for someone. After some time I walk into a room and find the person inside. Do I say 'which of the options below'?
a/ This is where you are.
b/ This is where you were.
c/ This was where you are.
d/ This was where you were.
e/ This is where you have been.
f/ This was where you have been.
(g/ some other options?)
I'm perplexed and can't figure this out. If I was to say anything it would probably be b/, d/ or present perfect (e/ or f/ both sound ok to me, which makes it even more confusing to me).
Could you please show me on some example situations when to use which of these sentences (if they are grammatically correct :-))?
