رضا: lets say for example you come to a game and see a message like "I know what you mean, that's too funny!" But you don't remember what you wrote and what they are referring to, so a quick look at the top message will show you what you said that they are replying to, instead of having to scroll the whole way to the bottom to see what it was you said. But I can see that sometimes you might want it the other way as well!
