Why did that wasp fly in through your window

Pay closer attention to the next insect which flies into your personal space. Why did that wasp fly in through your window? Is it going to turn round and fly out? If so, when? Is it going to eat your jam, or sting you? You don’t know. What’s more, no one knows. What’s worse, no one will ever know. You might say that the wasp makes up its own mind.
