Ok, I know that in 2nd cond. you use simple past in your sentence and perfect past is used when saying that something had happened before something else happened, but is it correct to say this? :
- If you realized while on your way to a concert that you had left the ticket in your living room, what would you do?
I instictively wrote that down because I was trying to communicate that the act of leaving the key happened before the act of realizing. But I'm not sure because I've never seen Perfect Past in a 2nd Cond. sentence before.
