Write a story which includes the sentence: ‘My friend was staring out of the window and paying no attention at all to what I was saying.’

Sure! Here's a short story incorporating the given sentence:

Once upon a time, in a small town nestled by the mountains, lived two best friends named Lily and Sarah. They were inseparable and shared everything with each other. One sunny afternoon, Lily went to Sarah's house to discuss an exciting adventure they had planned together.

As soon as Lily entered Sarah's room, she noticed her friend was staring out of the window, completely engrossed in her thoughts. Ignoring this, Lily cheerfully began, "Hey Sarah, I've been researching some awesome places for our adventure! We should hike up the nearby Misty Peak and witness the breathtaking sunset from the top!"

However, Sarah's mind seemed to be a million miles away. She didn't respond to Lily's enthusiastic voice and continued gazing wistfully outside. Lily could tell that something was bothering her dear friend.

Curiosity getting the better of her, Lily inquisitively leaned over to see what Sarah was so captivated by. Her hazel eyes widened with surprise as she saw an injured bird perched on a branch. It was struggling, its wings flapping weakly.

Lily gently placed a hand on Sarah's shoulder and whispered, "What's wrong, Sarah? You seem so distant today."

Sarah turned to face her friend, her eyes filled with concern. "Lily, look at this poor bird. It seems injured and unable to fly. I can't help but feel its pain."

Lily smiled, appreciating her friend's deep empathy. "You know, Sarah, we can always make a difference. Let's call the local animal shelter. They might be able to provide the proper care for the bird."

Sarah's face lit up, and she gratefully embraced Lily's suggestion. Together, they carefully contacted the animal shelter, explaining the situation and providing the bird's location. The shelter promised to send someone to rescue the injured creature.

As they sat side by side, waiting for the rescue team to arrive, Lily realized that sometimes, the most important conversations happen without words. She understood that her friend's apparent lack of attention was merely a reflection of her compassion for all living beings.

With each passing moment, Lily and Sarah grew closer, appreciating the shared bond of friendship that could transcend any barrier. And in that simple act of kindness towards a wounded bird, they learned that true friendship lies not only in words, but also in understanding, empathy, and the ability to support each other in both joyous and difficult times.
