Storm was not as liberal with affection as the Unicorn, and granted- several of the other little creatures in the Garden. He didn't hug, and he wasn't the type to hold hands, or hold people for that matter. His affection was gentle, and nurturing. Propping little flowers' heads up after a storm, making sure tiny leaves weren't twisted or caught up in the weeds. Hugs, however, were much too powerful a thing to simply be wielding at people- although he'd hardly stop someone if they asked. Though he'd have to question what that felt like. Cold and foggy, no doubt. Perhaps a touch overwhelming.
He couldn't help but chuckle at the idea. "Sure, I could accept that as a fair trade." he shrugged. "If you don't mind whatever it is being terribly gray, that is."
