Is AUTHOR wrong in the post ? POST : Background: 
I am 17 and do not have my license yet because of personal obstacles, so I ride my school's bus. I go to a private school and the bus driver drops us off at churches in our neighborhood. I live really close to my church (1 minute drive) so my driver drops me off at my house. Its in a neighborhood filled with nuclear families.

Now to the AITA:
Now my house is across the street from this family with 5 kids. Recently K1 has been outside and waving at me when I get dropped off. He likes automobiles so its pretty normal right. Well... when the bus moves, the kid moves. He started racing the bus and waving at it which is okay I guess, but he started another thing. He runs to the edge of the street/his driveway. My driver honks at him and it always scares me to death.

Literally like 10 minutes ago, he did this and I yelled over for him to stay on the sidewalk. I entered my house and out of worry I looked out of my window. K1 and K2 were playing, but K1 was being really mean and hitting the other. I got nervous, but then the OB came out and separated them. I was relieved, but then the kids went INTO THE STREET. My motherly instincts came out and I panicked because the OB didn't know. K2 was in the middle of the street while K1 was down a whole other street way. OB finally saw what happened and got them into the driveway. I walked out and I waved him over. He looked maybe 13 or 14 and he looked odded out.
Me: Hey K1 was almost out on the street when my bus was driving away and i just want to make sure he is okay. Could you make sure he doesn't go in the street.
OB: ok
He then looks at me weird and walks into his driveway with his brothers.
I feel weird cause idk if the father might go to my house and yell at me or something. I think I did the right thing, but I'm not sure OB thinks so.
So, AITA?
