Although I enjoy receiving and reading them, I very rarely pass along emails. I suppose it stems from my years of training to be computer tech and subsequently network administrator. I spent so much time studying, implementing and maintaining network security that it became ingrained in me to be cautious. But there are such great free antivirus and internet security programs that I don't need to be so vigilant now. Still, I only pass along jokes/inspirational stories to the people I know will enjoy them. Since most of my friends are online, most of them see the same stuff anyway through either the same or other sources.
Hubby passes along everything, mostly to his BIL in Quebec, who wouldn't get most of those jokes/stories otherwise.
When you don't like a thing, change it.
If you can't change it, change the way you think about it.
