I made a mistake confession

Hi all. I am upset. My cousin is mad at me because I screwed up his taxes. I said sorry, and it was kinda his fault. I will send them off ASAP, but he is suck a freakin drama king man. He gets ALL MAD because HE never checked his email. He gets on my nerves man. But I can't help but feel so sad. He trusted me and I let him down. I tried saying sorry, but that boy can hold a grudge even longer than me. And I have been known not to talk to people who pissed me off when I was like 10. Still, I am gonna mail it in, He will have to wait awhile to get his money, but I mean, he will not be mad at me if he gets his money eventually. I hope not anyway. I feel like such a loser man. Adrian always has had the ability to make me feel like that. But i know he loves me, i just made him mad. Still it hurts.
