Filter. It's kind of an odd word if you toss it around in your head with some added coffee for a minute. Let's see. Filter, as in, filtering my thoughts before they form words or letters on a page to relay my mental images and thoughts? Or about a coffee filter that is in my coffee pot and part of it is probably floating around somewhere in the void of my mouth? Or are you referring to a filter as in a cigarette or any other smoking apparatus that might be entering my mouth with a filter? I don't know but I'm having trouble filtering your question and approaching in a filtered fashion you might desire. Please do assist me to answer your inquiry with the appropriate filter. I'm very confused.
