Oh no!

You were in the library, looking for a book. You seemed to struggle to find a book you like, so this would be hard for you...

Then, you found a book section, and you tried to get a book from the top shelf, but dang it! It was too high. You grabbed a chair and went on top of it to get higher, but after a few seconds, you lost your balance and fell down.

You groaned in pain and noticed that your knee had a small cut, but someone walks up to you and helped you up.

"Oh my God! Are you okay?"

It was Ruby, one of the friendliest students in the school. She seemed to be concerned of your injury, so what would you say back to her?
