I got hurt

I was too careless! Sorry~Mom & Dad.
This is the orgin of my wound:
Tonight, I wanted to share my guava with my roommates, so I cut it into small pieces.
But the guava was so soft that I cut my hand  accidentally.
All of my roommates were very nervous, and so did I.
After our housemother helped me strap my wound, I felt much better.
Thank you! You're so kind.
