There are some promises that are unspoken. We call them expectations.
Parents are expected to care for their children. And when you have created something, you are expected to take pride in it, take care of it, value it.
It expects those things from you.
But when you have created something, you are also responsible for it, and anything that it might do. For all of your hard work, for all of your dedication, it may make itself impossible to appreciate.
