Re: pointed out to each other shoes
Neither. They each showed (pointed out) these things.
If you and I were walking in a farm, we might have a conversation like this:
Oh, look - there! What a cute lamb.
Oh yes, it's cute. And look at the little piglets.
Piglets are cute too. Oh, look over there -- thosehorses are huge!
I've never seen such big horses... but look at the size of that bull!
And so on.
We pointed out to each other piglets, lambs, horses, and animals of all sorts.
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.
