We thought we could make it all the way through without crying, but we could not! We found this PSA from the "Royal Dutch Guide Dog Foundation" that is so poignant, it's worth sharing. It opens with a wounded soldier in a war zone who's on his back and frustrated because he can't get up and help a fallen child who's a few feet away. Just then a fellow soldier comes over to comfort him, and he starts licking the guy's face. Then it cuts to the present and you see that it's actually a guide dog who recognized the veteran's nightmare and is waking him up. The tagline says it all: Quote, "We train dogs to guide people with a trauma out of a nightmare, because we not only help people who cannot see, but also those who've seen too much."
