is this sentence all right? Can I say "miss working with you'
I miss working with you and I hope one day we will have the chance to work together.
Sure. It would sound better to me if you added "again" to the end.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
