I can't decide whether this sign means:
1. "Beware, O public, for there are bees about."
2. "Beware, O bees!" [or, Beware if you happen to be a bee]
3. "Hey public, FYI these bees are busy being all bewaring, just thought you'd like to know?"
4. "Beware if you like semantic clarity because I plan on keeping you mystified."
