He didn't know how long he had spent trying, but he didn't manage to find any access that would allow him to return to the relative comfort and safety of his house.
As Nathan cowered and shivered beneath one of his mother's azalea bushes planted against the brick exterior of the house, he noticed something else. A large snowflake drifted to the ground in front of him. He raised his head and saw that the air was filled with falling flakes of snow.
"Ohmygod!" Nathan squeaked. "I've got to get back inside."
He worried even more as the snow began to accumulate and drift over the yard and sidewalk.
He kept waiting for Billy and Arush to exit, but they never emerged from the house. In fact, a few hours later, the shivering mouse watched as gigantic teenagers walked up the path to the front door. They easily scaled the steps that defeated the wee mouse's efforts to regain entry to his home.
"Those idiots!" Nathan squeaked. "Even without me here, they're still using my house to have their party!"
The snow continued to fall, forming huge drifts. The snowfall soon made any type of travel through the yard next to impossible for Nathan in his tiny mouse body. He decided that, ignoring the fact that dozens of his friends partied only a few feet away, he needed to find shelter for the night. He eventually tucked himself into a snug crevice beneath the foundation supporting his mother's towering concrete bird bath.
