Bobbie... I totally understand your losing it and ripping the poster down. I wouldn't have done it, but... I spend a lot of my time stopping my husband from doing things like that. If they'd arrived at our apartment at 1am it would have been my husband being arrested... for losing it.
I hope the rest of your pregnancy is stress-free. It's extra hard keeping calm when you're 7 months pregnant and during the summer months. Good Luck with your pregnancy.
