Actually, you probably don’t make these internet mistakes but if someone you know does, point them in the right direction. Kindness isn’t just about helping old ladies across the road, it can be about stopping friends and family from making fools of themselves on the Internet too.
We’ll start off quite basic but I think this is only a mistake parents and grandparents make on the Internet (or in texts). When you type in caps, it’s akin to shouting. No one likes being shouted at.
