Interesting thread! This is literally not something I ever knew existed until the past few weeks. It certainly wasn't something we looked for, or was called to our attention, as we were doing college searches all last year for two incoming freshmen. However, I think it's great.
My DD takes advantage of everything, pretty much, going on at school. And there have been lots of "little things" that have made her adjustment to college just a little bit more fun and less stressful. I hadn't heard about puppies (she would've been there in a heartbeat!) but I've heard about snacks around school, BBQs, root beer floats, pumpkin carving, other arts and crafts (which she's all about), etc. These things made her smile, relax a little, meet new people, and undoubtedly helped her adjust to her new environment. As such, I can't see the down side. As far as coloring books go, interestingly, the day after the election, she was passing by the "coloring book section" in the student union building, so naturally, as always, she stopped to color a bit. The strangest thing was that the coloring book had a very vulgar, almost shocking, term on the outside of it. She noted it seemed an odd contrast to what was supposed to be a soothing activity, but she colored for a few minutes anyway and went on her way.
I work in a very stressful environment. Fortunately the leaders in my organization recognize that day in and day out stress negatively affects people - not only in their moods, but their actual health. (Over the years I recall at least two suicides, many addiction disorders and stress-related illnesses of coworkers.) So they take various (and numerous) steps to help us cope with stress. Dr. Herbert Benson of Harvard Medical School is the father of Mind/Body Medicine. I've been fortunate enough to take one of his seminars about the long term effects of stress in our lives, which, according to him, is cumulative - its build up can actually push someone who's prone to illness over into a disease state. Many of us are walking around day in and day out in a highly stressed state. Just read the news and we can see the effects of it. Not really sure why anyone today would begrudge others for helping people learn to de-stress. As a society we could all benefit by working on it more so that we're not all so tense all the time, IMO.
