An iFriend posted this video on Facebook. I'm sharing it here because there's just something about watching people help each other (even in something that's very clearly dramatized) that cheers me up. Admittedly, it also left me a little sniffly, so if you don't want your co-workers to catch you crying you might want to watch it at home, or at least make sure nobody else is around. (I'd pretend like I'm the sort of manly man who doesn't get reduced to tears by, say, this sort of music video - or children's cartoons, for that matter - but I've been a parent for over five years now. If I ever had those sort of pretensions, or even a tiny little shred of personal dignity, they're long gone now.)
There you go. Hope it cheers you up, too.
