Nah don't worry it's indeed sometimes hard to tell when someone is joking or not, mainly because there are so many dumb people in the world that you can never be sure about ones intentions, not from a few words at least. My post wasn't complex enough to be considered a clear joke anyway, it's my fault. And yes I find myself using emojis more than I like, they definitely can change the whole meaning of a certain sentence, they show the tone you want to deliver your statements with, which is really fascinating but I had incidents when they've been taken wrong. :)
