Today, I fell while riding my bike.
Are you injured?
I may have to see a doctor about them.
Yeah you should treat your injury as soon as possible. I hope you learned a lesson or two from the accident. You should be careful while riding your bike.
I'm going to do my best to avoid bike accidents in the future.
It's good that you're going to be more careful going forward. Riding a bike can be dangerous if you aren't careful.
