Its 4:43 am and I cant go to bad cuz something bad happend to me?

yesterday morning me and my friends were like having a breakfast and like all of a sudden this lil B started a fight with me. I was eating Capn Crunch she was eating Apple Jacks and like she kept telling me to eat faster cuz my cereal was getting soft. Like wtf does it have to do with her? Its my cereal I eat it the way how I want it but she was like " noo its not Capn Crunch anymore cuz its not crunchy booo hoo". So I told her F this I dont need to take this crap from you " I m leaving" and I left and like she was " boo hoo I m leaving too" and my other friends were saying we are F*ked up and stuff like that. Like wtf is her problem? why did she started that crap anyway? I cant get it out of my head
