Mourning is something that many western cultures don’t do well. Unlike our Mediterranean neighbours, or more expressive people from tropical climes, we think holding our feelings in check is a Good Thing. “Stiff upper lip, old boy.”
Christians are often even less inclined to mourn than others, because we have a sure and certain hope that our departed have gone to be with Jesus. We use terms like “promoted” to express our positivity. I was even once told by a family member at a funeral that we were not going to cry, because it was a happy day of celebration for our friend who had gone to a better place. Which left me with a lot of grief and no outlet for it. Sometimes we need to express our emotion and have a good wail.
