Speaking on his cell phone while waiting in line to buy stamps Monday, Brad McCall assured girlfriend Stephanie Green, as well as 14 customers and six postal workers at the Jefferson Street Post Office, that he will do everything in his power to change. 'Things have just been so messed-up for me lately with all the stuff that's been going on. I know I haven't been myself,' he explained to Green and the crowd of strangers. 'But all that's gonna change soon.' McCall also told fellow post-office patrons that if getting a place together is what it takes to make her feel like he is committed, he is 'totally willing.'
