Today I leaked and got really upset. My friend Antony was asking me questions about the girl he liked. "Why don't you guys make eye contact?" WTF. I was really bitchy and kind of cussed at him. lol i mean REALLY cussed at him. i feel bad about it. how can i make it up to him, without telling him exactly why i cussed him out?
