We expect the truth but those who know it may not have any reason to tell us and good reason not to.
We expect a peaceful environment around us but it only takes one person to shake it.
We expect that others will respect our rights but for some, ignoring rights is the way they achieve what they want.
About the only things that cannot be taken from us are our own thoughts and feelings. To expect anything beyond that is to feed our disappointments.
In the words of Buddha, when you cease expecting, you have all things.
