There is one thing that happens to me often now that I am a parent. I'll get into the elevator or walk around on the street and reach into my pockets. Most of the time I'll find something that reminds me of my kids. A pacifier, a snack bar wrapper, or often a small toy. I had put them there at some point while attending to them. They are nice little reminders and always make me think of the movie It's a Wonderful Life.
