First of all, I was under the impression that you were using the term "you're excused" in a sarcastic manner. I was using the term as if to say "a moment of your attention, please", as it could be inferred that I was not asking for my comment to be excused from the discussion.
Secondly, you typing in all lowercase to distinguish your comments from memes makes no sense. Memes are images with a caption to accompany them, while on the other hand, comments have no such thing and are simply text (depending on how you format said comment, such as inserting a link, in which they are still text but lead you to a website/part of a website). Comments and memes are very much different from each other in appearance, thus there is no need to type in all lowercase (unless you mean to further distinguish the two from one another).
