The tinkerer of the current group TechTandem, I can fix some things due to technologies used by our group. 

About myself:
                   PLEASE DON"T CALL ME KILLJOY! Remember this one: we shouldn't bully somebody by means of direct/indirect message to him/her. Have some empathy - if we're going to be bullied, would we have wanted to let it happen? That's why I could just enter the scene and end all of the joy you had. 
                   I AM SERIOUS: The life isn't about joy yet; it's suffering. Remember, joy only appears when we achieve something from our seriousness. I can't be jolly too, because it creates a disruptive noise for everyone (I can tend to laugh at a very painful pitch), so I don't you to be hurt.
                   I AM A TINKER: Please - it's not Tinker Bell! It's really Tinker - which means to casually fix something. We can use our brains to solve a problem. Sometimes, I may act odd, but that's really the system in our group - call concealingly.  If we don't call to each other concealingly, then we can't be agents that can bust out problems.
                                                                                    - Tnkr.
