Be careful when you are cutting your birthday cake in case in contains a nest of spiders. Lunging at spiders with a knife might make them misinterpret the situation.
It's someone's birthday today, maybe not yours or mine but it's someone's; it's commonsense. I know lots about people and most of what I know about people I learned from spiders. Though wasps, when you think about it, are a kind of winged spider. Spiders don't hum like wasps, they just whistle. Nobody really knows why.
