You come here trying to take me away from my (whatever I'm holding) just so you could tell me about this particular event that isn't worth my time and you know it. Yet you continuously think that I will be interested the next time so you once again return with inane babble for the average teen that won't entertain me in the slightest and have me waste 30 seconds on this speech.
If its someone younger bothering me then the classic, "Don't bug me kid." always works. It undermines them and makes their actions seem dumb.
