So apparently it's not really considered okay to show up to your 9am dress rehearsal (for your first concert with a semi-professional chorale in a major city) late-ish, in sweats, and still reeking of alcohol and the cologne of some rando from the night before...? That may have flown in college, but this is the real world, lady. Sack up. GROW up. Start taking some responsibility for your choices, and stop sabotaging every good thing that comes your way. If you want to sing, maybe start being on time to rehearsal. Being well-rested and sober couldn't hurt either.
Also Probably Stop Smoking So Much,
