theyd possibly get seperated for one day,but then they get happy again

Of course they'd work it out!

I agree with both of you. =) I think they'd kind of be mad/sad for a day or so, then they'd both apologize and cuddle real cute that they always do.

I'd like to see some more ideas of what could happen.

Do horses even have arguments?

argument? about what? grazing places and springs? :))) well if we think better, they had something like this when they were both pulling one end of that rope :)) but i can't think of another situation of this kind..:-??
