In a way I'd probably be happier if I ever said boo to a few geese here and there, but at the same time I'm not sure if I could live with the growing reputation as a goose booer that this might give me.
I suppose that the secret is to pick your goose, pick your moment and get the timbre of your boo just right. That's how to say boo to a goose. As long as I don't trust myself to be able to judge all of those factors just right, it's probably best I keep up my never say boo to a goose philosophy.
Geese can rest easy. But only metaphorical geese. I was bitten by a goose as a child and I carry resentment of geese to this day. Those birds have a bad attitude.
