Has anybody ever gotten into a argument/debate with CLOSE MINDED ppl?!?

Yer micturating into a stiff breeze here. Don't bother. The definition of "closed-minded" is that they aren't open to new information. They know what they know even if it's wrong. Just get some eye drops and keep it secret from them. Although, ironically, having to keep it secret leads in all kind of subtle ways to willingness to use harder drugs.
