Sorry, ozone layer

Every evening while eating dinner, we have a family tradition of "best and worst parts of your day" At this time, we go around the table and state these. It helps us all keep in touch with each other etc.... The other night, it was the middle childs turn for this. Her best part "no homework" and worst part " I had the farts today!!!" Then the son pipes up and says he did too. At this point I begin giggling hysterically because I know the culprit immediately. I had sent Fiber One granola bars in their lunches. I knew this because I had the same problem from them and this is why I gave them to the kids, thinking they wouldn't affect them as they did myself. WRONG!!! Man, am I in trouble over that one. Methayne gas destroys the ozone layer.......SORRY OZONE LAYER!!! No more Fiber One bars in this house.
