wishy-washy?

this morning carl and i were talking about optimism. a book said that you should be an eternal optimist. carl said he disagrees with that.

"i think that's very wishy-washy," he said.

um. what?

i asked him if he knows what "wishy-washy" means, and he said, "i guess not :)"

i told him it means "indecisive". and he said, "oh. i guess i mean cheesy."
