One of the most thing that I truly hate in emails is sending out chain mails which is not good. I feel irritated with those people who loves sending useless matters. If you will open it , there you can find many things that you need to do so and if you will not do then it says some bad words against you or saying bad beliefs.
So this is not really good. I hate this stuff , I never tried forwarding chain letter that has not good content. Well, I am not sure for others maybe they love sending or they are just obliged to do because they are afraid of what the content say so.
