bumped into...

Alex was walking to school alone. He was aware of the danger of a boy walking by himself to school, so he was walking quickly. Alex glanced at the time on his phone and realized he was already late, so he decided to run.

While Alex was running and checking the time on his phone, unaware of what was in front of him, his head suddenly collided with something,or someone. The impact knocked him backward and sent him falling to the ground.

"Aaah, damn it!" Alex groaned, rubbing his head to ease the pain of the collision. He looked up to see what he had crashed into.
