Alex was about to say something to the effect that while it was his dream, he was doing this for Lumi, thus she should have some say in it as well. Though that thought disappeared as he eyed two horses before Lumi. Looked like she really was good at this dream thing. If there was one thing Alex loved, it was animals. Didn't matter what it was - he cared about them all the same. He kept on smiling while rising to his feet and examined the two horses. That's right, Lumi was into horseback riding, so of course she would want to give that a try in the dream.
Petting one of the horses, he looked over to the blonde, an adoring glimmer in his eyes. "Never really ridden one before, but there's a first time for everything, right?" He did his best to jump up on the horse, failing for a bit before finally getting on properly. He was willing to give this a try for Lumi. Anything to see her smile and laugh. Girl deserved it. "Alright then... where to?" He nudged the horse on over to Lumi's steed, watching her and waiting for her command. Besides, dreams were boundless, right?
