A simple thing I like to do to add a bit of joy to my week is buy a single flower to put in my home. My favorite is a white rose, but you can choose your favorite.
If you do not have a bud vase, you can cut the flower where the stem meets the bud and float it in a bowl. This is a simple and easy way to bring a little light and love into your home.
If you do not want to go out and buy a flower, you can borrow one from your garden or a nearby field.
