Uh oh! Now you've done it. You opened your mouth and agreed to host the next neighborhood get together. Unlike Sunday football and a cooler full of beer, this is your first real "grown-up" party. It's no wonder your spouse isn't speaking to you! Judging by some of the parties your neighbors have hosted you'd best get a crash course in how to tell the difference between a "martini" and a "mimosa." Does it matter? You bet it does!
