because of me

Three seconds ago my mom said she was going to donate money to the "Idol Gives Back" thing and me being the jackass that i am decide to make a dumb comment... "Whatever you can donate isn't enough"... she got so upset with me that she wouldn't donate. I hate how i cant censor everything that goes through my head. whats my problem? because of me people that could have been help are not going to get any.
