Okay, first of all, you may want to watch your diction. Saying things like, "you cannot be serious all the time" and "I need to know whats up with you" is indicating that you hold some kind of authority over me when the fact is you don't.
Second, I'm serious a lot because of the immaturity. I used to be the most Random Person in the SB, but other people saw me doing it and started doing it too. S'okay, nothing wrong with that. However, they did it on a "non funny" level. Just saying Random things that weren't relevant or funny. The timing was all off and it completely ruined the point of being Random. Then it got to the point where the un-funny Random things became immature Random things. People talking about sex jokes, and disgusting stuff that I found offensive. If I find something offensive, I'll tell people. (Unless that Person can't take criticism) But this trend spread fast and thus being Random became unappealing.
Now, since everyone became Random and it was getting to an uncomfortable level, I naturally found mature conversations more stimulating. Not to say that you can't be silly every now and again, but its no longer appealing to me when everyone's doing it AND they've taken it to a level I don't like. If mature conversations got that way, I would probably stop doing that too. You can say I'm boring and rude, but the same has been said a lot about people who act maturely. Little kids (not saying you're a little kid, just making a reference) find that what adults do is boring because it doesn't pertain to their "fun" and they find them rude because they won't agree that their "fun" is actually a better "fun." I actually came to Zelda Dungeon to have stimulating conversations about the series that I can't get with the rest of the world cause they're not Zelda nerds.
You say you've only seen me serious, when there are plenty of people on here who will tell you that I've cracked jokes plenty of times since I became serious. And my seriousness is not going to stop. If you're afraid to joke around me, that's probably because you should be since as I take alot of things offensively. I believe in God and have a strict moral code for myself, but I can also tell when things just shouldn't be said to others who don't have such things. If you think someone can't take a joke, then its best to not say it. And the fact is, if I had to choose between being respected and liked, I'd probably choose respected. But honestly, I think that I'm liked and respected around ZD. Not to hold myself on a high horse, but a respected Person who isn't liked wouldn't get as far as a Person who is both respected and liked.
