" Should is a dangerous word, a warning sign that we’re crossing an important boundary and veering into book bossiness. Should is tangled up with guilt, frustration, and regret; we use it all the time, many of us to speak of the ways we wish we could be more, do more, or just be different. Or that we wish our friends could be different, and they would if they knew what was good for them.

Should is bossy. "
