This great idea is perfect for Father's Day, or for someone special's birthday, and the best part is it's totally free!  It's called a Blue Monday Jar, and the idea is that after spending a weekend with mom and the kids, dad feels blue when he has to return to work on Monday. Here's how to make it: Take a small clean jar with a lid, such as a baby food jar. Decorate the jar any way you choose. Cut 52 pieces of paper into fortune-cookie paper size or a bit larger. On each slip, write a reason you love the person, or a wish for the week, or a word of advice. Then, every Monday morning, the person pulls out a slip, reads it, tucks it in a pocket, and feels a little less blue. My husband loved his, and he never forgot to pull out a slip on Monday!
