Our most constant relationships, like marriage, require our most constant deposits. With continuing expectations, old deposits evaporate. If you suddenly run into an old high school friend you haven't seen for years, you can pick up right where you left off because the earlier deposits are still there. But your accounts with the people you interact with on a regular basis require more constant investment. There are sometimes automatic withdrawals in your daily interactions or in their perception of you that you don't even know about. This is especially true with teenagers in the home.
