I think August wants to go to school because maybe he wants to make new friends. August laugh/cry ,maybe because when  august meet the other 3 kids one of them was really mean  the other ones  where nice  maybe something  make August laugh , maybe something  like meeting new people might be scary  and other people are mean to you anyone could feel to cry that might be the laugh/cry.  I thing August is feeling nervous because he haven’t meet other kids that he didn’t  now that will be pretty nervous , another feeling would be   happy he could make new friends.
