Are there really that many?

In the grand scheme of things I live a pretty sheltered life. My circles have always involved friends from work, church, Christian small groups, college friends, a few professional organizations and neighbors. So while my circle of people aren't overwhelmed with the horrific and traumatic aspects of life, they all still have pain. Are there really that many different hurts for these groups of people to which we should be sensitive? I didn't really think so (as shared in the last post) but let's make a list:
(There are a lot of varieties and differences in sensitivities so I'm listing many separately that might often be grouped together.  For example, the way women and men deal with a particular situation can be vastly different.)

Wives going through infertility treatments
Husbands going through infertility treatments
Couples who miscarry

And that's barely touching the surface! Put yourself in any one of these situations and you can understand how so many people are often hurt by our words, conversations and actions.
