Not one, but two:
I took this photo yesterday. I love the way roses glow in the light of early evening. This was a "miniature" rose bush that I bought years ago, and now it's chest high. The flowers grow in bouquets.
At school the other week, we did chalk drawings for Earth Day. This one was my favorite.
These are the kinds of little things that brighten my day. I don't always have the chance to take pictures of them, but I try to notice them and appreciate them every chance I get.
