People like to vent their spleen. On social media, you can come clean. Express thoughts, opinions without consequence? For what it's worth, give your two-pence.
It’s a right of course, to have one’s say. But surely we can do it with civility? Cruel words can sting, and wound and stab; we’re not all equipped to slip the verbal jab! So take some time before you send your words abroad, and remember - the pen is mightier than the sword.
