Does 'Can Serve at 18/19' Mean 'Should'?

A Mormon boy from an affluent neighborhood in Utah, barely 18 years old, will leave a few days after graduating from high school for the crushing poverty, suffering, and misery of Sierra Leone. This isn’t the plot of an off-color Broadway musical. It’s going to happen in a couple of months to a real person.[1] He’s not going to experience mere culture shock; it will be an entirely different world, a different universe. Nothing in the boy’s lived experience up until this point is going to have prepared him for even the smallest percentage of what he is going to observe landing there. I hope and pray he survives! There isn’t much difference between an 18 year old boy and a 19 year old boy — both are teenagers still, both usually as green as can be. On paper it’s a wash.
