Once upon a time, there was a grandma named Lily who loved to go on adventures with her grandson, Ben. One sunny afternoon, they decided to go hiking in the mountains. As they explored the beautiful trails, Grandma Lily suddenly felt the urge to use the restroom. But there was no restroom in sight, except for a scary-looking porta potty at the edge of the trail.

Grandma Lily had never used a porta potty before and was terrified. She imagined all sorts of scary things lurking inside. But she really had to go, so she took a deep breath and opened the door. Inside, it was dark and smelled strange. Grandma Lily hesitated, but then she thought about Ben waiting outside and found the courage to go in.

While Grandma Lily was inside, she heard a noise that made her jump. It was just a little squirrel hopping on the roof of the porta potty! Ben, who had been waiting anxiously, saw Grandma Lily's scared face through a little window. He quickly ran over and shouted, 'Don't worry, Grandma! It's just a friendly squirrel saying hello!'

With Ben's encouraging words, Grandma Lily felt braver. She hurriedly finished her business and stepped out of the porta potty with a proud smile. Ben gave her a big hug and said, 'I knew you could do it, Grandma! You're the bravest grandma in the whole world!' From that day on, whenever Grandma Lily faced a new challenge, she remembered the courage she found in that little porta potty and knew she could conquer anything!
