Thank heavens for those dedicated, young, white voluntarists. The point is they were not "voluntourists", they really did sacrifice to help your grandmother - as opposed to showing up, getting in the way while doing a few trivial things for a week or so, playing much of the time, and otherwise squandering money which would have been better just sent to the orphanage outright.
