once when I was a child I went to PIzza Hut with a friend of mine, and as was my habit then, I set my enzymes out next to my plate so I would remember to take them - and the waitress came up to me and asked if I had CF because someone in her family had it and she recognized the pills.
Then, about a year ago, I was out at a bar and this acquaintance of mine - one of those friend of a friend of a friend kind of people, came up and started talking about CF to me, telling me about his best friend who had died from it and stuff - and I thought it was kinda wierd for him to just start telling me this (he'd been drinking), and finally I asked him if he knew I had Cf and who told him - and he said no one told him, he just recognized it by the sound of my cough.
So that's my stories. I have yet to catch someone popping enzymes - though if they are as good at me about being stealth with taking them, then they will never be seen!! <img src="i/expressions/face-icon-small-wink.gif" border="0">
