I started crying in class

My parents are split and my mom has me most of the time, but my dad picks me up every Thursday so we can hangout, and this seems really nice but my dad is a really hard guy to get along with, hes always angry and refuses basic necessities, like food for his house, anyways to try and get along with him i have some cds from bands we both like, and i had just gotten a new one, and i know its his favorite bands even though he never told me so i was really excited to show him and listen to the album, but he texted me in class today and said he wasnt coming to get me today, and i dont know why it made me so upset but i started crying in class, and he didnt apologize for cancelling it just sucked.
