"Text me when you're heading home." We've all heard it, and we've all forgotten to do it. Sometimes, even when we do remember to text, the unexpected happens. We get stuck in traffic, get caught up talking to a co-worker while trying to leave the office, or suddenly remember that we should stop to get that one thing we really need at the store. These events can be hard to communicate, and frustrating for family members who are trying to time their activities around your arrival at home.
