I'd respond with something like: "If someone recorded a show and doesn't want to know the outcome, they shouldn't go online (or listen to the radio or tv talk shows, or for that matter conversations around the water cooler at work or in line at the grocery store). I see headlines about last night's tv shows when I first go online in in the morning. I like to talk about my favorite tv shows, so this is fair warning to all my friends: Stay away if you don't want to be spoiled! :) "
There have been times when I've posted something on MY status (not as a comment under someone who has just sent me a Farmville request) that says, "Just for the record . . . I don't "do" Farmville or lots of other stuff on FB. I'm hiding all requests or comments about those things."
You could maybe put a generic post that says, "I sometimes discuss TV shows that have already aired. It's not my goal to be a "spoiler" - but if you don't want to know what has happened on a show that's already been aired, you should hide me on Facebook, right after you avoid your television set, computer, radio, or other people who might spill the beans."
Follow it up with the emoticon of your choice.
I had a funny encounter this morning when my daughter and I were at a yard sale. We were both wearing Birkenstocks which plays a part in the following conversation, although I have no idea why. There was a young girl, around 8 or 9, and she asked, "Are you both book illustrators?" I lied, "Why, yes. How could you tell?" She answered, "Because of your shoes." :laugh
I just do my best to avoid this place and twitter, FB etc until I have time to watch something. If I am spoiled, so be it but it is fun to try and keep unspoiled. I watched the AR finale one day late and unsure as to who had won. I found out by accident who had won Survivor but it didn't ruin anything for me.
"Fun" experience last night.
I take 2,000 milligrams of Niacin every day with my doctor's approval; my cholesterol is just a little high, and I am fighting so I don't have to take statins to control it. For a couple of years, I've been taking one brand. I was at Costco the last time I needed some instead of Sam's (where I usually get it). The new stuff looked a little different, but to my non-medical mind it didn't make a difference. Wrong.
My old standby is "flush-free." The new stuff is "time-released" . . . but after I turned bright red (3rd degree sunburn red) and my skin getting really hot, I re-read the bottle and realized it was NOT "flush-free." After a benadryl and about an hour, things calmed down.
Reminder: READ THE LABELS.
I've come to realize that a lot of people don't read the most obvious of labels and I, like you, through personal experience have come to realize how important that is. One day, after having been on a medication for months, deemed to read the insert and the info that is ATTACHED to the bag that my prescription had come in. I learned things that I should have known all along, but didn't "waste" my time discovering. I was bored, sitting at a table, and decided to read......:omg The only thing the pharmacy people generally will ask you is if YOU have any questions and, thinking that you already know it ALL, you say, "No." WRONG-OLA!!!! I encourage everybody to take the time to read what you are given with your medications/vitamins. You just might be surprised at what you learn, and kick yourself for not having done that way before you did! I renew my knowledge every so often to see if they've snuck anything in there that wasn't there before or that I may have forgotten.
I am a good one for teasing people and saying "Reading is fundamental!", with my direct stare. I, now, look into the mirror and say that to MYSELF!!! :lol
