Your dad never cared for you, he often ignored or never talked to you. He didn't even care enough to take you to school, so you don't know a lot of things, such as how to talk, walk, write, or read right

You were going down the stairs, but since you have trouble walking, you tripped, and fell down, getting really hurt

He heard the thuds, and went to check, and saw you, crying, hurt

He felt a little bad, and only a bit worried

"Um.. you okay? What happened?"
