I love this -- it sounds good in Spanish ("cuidate") too.
Maybe it's just age, but I've become fond of telling people to "be good."
It's intentionally vague -- it could just be a grammatically poor version of "be well"
Or it could be a suggestion to behave yourself (ish).
It doesn't explain itself and that's my favorite part.
It might be the most middle-aged thing I’ve ever done, but I joined a dragon boat paddling team with a bunch of teachers and I’m obsessed. The boats look like carousel animals! So many magical things about paddling in sync with 30 other people, being out on the water, seeing eagles and blue herons, plus a core workout as good as the Pilates reformer. It’s the freaking best!
