Bill couldn't help but laugh as he watched Mike. There was no reason for either of them to really be quiet or to make such an elaborate show of stealing ice cream. The house was quiet which meant the others were either out or somewhere a little further away. In spite of the fact that they were, probably, safe he covered his mouth with both of his hands to keep the giggles from escaping. Once their stolen treats were assembled he helped Mike grab a few more things before following him up to his room.
Mike seemed to have settled in pretty nicely since the last time Bill had been in his room to talk. He didn't seem as worried about bringing food and drink into the room. That was nice to see. Bill was certain he would've stressed out over having something as messy as an ice cream cookie in his room before. He would've been too worried about the things melting and someone getting pissed off. He hoped this meant Mike was comfortable with the new surroundings.
Slipping off his own shoes he moved to carefully sit on the bed along with Mike. They hadn't eaten all of the ice cream so, maybe, they wouldn't get into too much trouble but... "You know, if this was Bev's she might still kill us." Bill said as he picked up one of the cookies. Oh well, if he was going to die over stolen ice cream he might as well make the most of it.
He sort of hoped it wasn't Bev's. Even if it was, however, the bite he took was more than worth it. His attention was drawn from the ice cream back to Mike and he nodded. "Well, yeah. It's a ball. How often do you think we'll be invited to those?" It was either going to happen a lot or not again. He'd err on the side of caution and go to this one. "Besides, I had a little group going to actually find stuff to wear." It was a good thing Richie had a car. There was no way he was taking that many people on the back of Silver. "Are you going?"
He was trying to appear nonchalant about the entire thing. He was curious because he was a friend. A friend who Bill had a crush on, sure, but still a friend. He also knew Mike was probably being bombarded by interested girls and guys. Bill was just curious if he had asked someone or not.
