A personal favorite among this set: a little gray book called Dangerous Women, which features found photography commemorating mischievous girls. I like it as an alternative to a love poem.

Other ideas, no wallet necessary: write, paint, cook, wander. Plant a tree, make a fort, eat cookies for breakfast. Dance. Sing. Play hide-and-seek. Whatever you do, have a happy one.
