"Wouldn't you wanna do the water rides first? Then wind from the other ones dries you off." He didn't know if it would actually work that way, he'd never been to an amusement park with water rides, but it made sense in his head. When Eddie took his hand Richie curled his fingers to hold on. Partly because he wanted to return the gesture, and wanted to hold Eddie's hand, but partly too because he wanted Eddie to know that he did want to be there, with him, even if he had gotten nervous about it. And even with all of the words that swirled in his head at any moment, Richie was pretty sure he wouldn't be able to piece together the right ones to say that out loud.
"Does that make me one of the garbage pail kids? Do I get a card?" Eddie's mom would have had a kitten if she ever knew Eddie even saw those cards, but Richie had bought some and showed them off anyway, because of course he did.
