DEAR ABBY: I lost your cookbooklet collection! My family and I have really enjoyed some of those recipes. I have loved all the ones I have tried, but my favorites are the desserts. Particularly noteworthy is your Peanut Butter Pie. It is yummy! Please let me know how I can order the booklets again. I need them because I'm having a family celebration for Father's Day. \u2014 SWEET TOOTH IN PHOENIX DEAR SWEET TOOTH: You and I have something in common \u2014 our affinity for desserts. I have made the Peanut Butter Pie for guests many times, and it has been well received. The last time I prepared it, I thought I'd try to "de-calorie" it. I drained some nonfat yogurt in cheesecloth until it thickened and substituted it for the cream cheese. It worked beautifully. My guests couldn't tell the difference. For readers who might like to try it, here's the original recipe: HEAVENLY PEANUT BUTTER PIE CRUST:\u00a0 2 cups graham cracker crumbs 1\/4 cup butter (1\/2 cube), melted 2 oz. semi-sweet chocolate, grated FILLING: 1 cup crunchy peanut butter 1 pkg. (8 oz.) cream cheese, softened 2 teaspoons butter, softened 1 cup sugar 1 teaspoon vanilla 1\/2 cup miniature chocolate chips 1\/2 cup salted peanuts (optional) 1 pkg. (8 oz.) frozen whipped topping, thawed In medium bowl, combine cracker crumbs, butter and chocolate; mix well. Reserve 1\/4 cup crumb mixture to use as garnish. Press remaining crumb mixture onto bottom and sides of 9-inch pie plate. Chill. In large bowl, beat together peanut butter, cream cheese and butter. Add sugar and vanilla. Blend well. Stir in chocolate chips and peanuts. Fold in whipped topping. Pour into chilled crust and garnish with reserved crumb mixture. Chill overnight. Serves: 8 DISCIPLINED people.

He's 50; we are in our 60s. He regarded "help yourself" to mean it was OK to drink our liquor from early afternoon to bedtime. How can we have some control over this situation without causing a scene? \u2014 BAR'S CLOSED IN NORTH CAROLINA DEAR BAR'S CLOSED: Put a lock on the cabinet where you stow your liquor, or move it out of the house entirely when you know he's planning a return visit. And while you're at it, have a serious conversation with your daughter about her boyfriend's insatiable appetite for alcohol, because it could have a negative impact on her future.
