Well, I'll give the unpopular opinion, but I speak from the experience of having a 15.5 year old daughter myself. I smiled as I was reading this because I was interpreting what was between the lines and what hadn't been said.
First question - why is there an alarm clock set to go off in the living room? Did you set it, and were you supposed to shut it off and/or be reminded of something by it? Maybe that's why this person was angry that you didn't come in and shut it off while he was trying to talk on the phone. Maybe it's happened before.
I smiled at the "after a while of just sitting here, browsing through new posts", because that is my daughter's interpretation of several hours spent looking at Pet Talk and other things on the Internet. Also, you telling him "I'm busy doing something" is pretty funny, because you were sitting on your butt in front of the computer, picking a possible flea off a dog's head, not working on the cure for cancer in your labratory. In other words, it wouldn't have killed YOU to go turn off some stupid alarm clock going off in another room either, but it seems to be a symptom of your age group, that it's more fun to argue than to just cooperate. This type of situation happens several times a day in our house, and when my daughter tells me she's "busy", the only thing she's busy doing is being obstinate.
It's possible that this person you describe as BR is a complete jerk, or maybe you've finally gotten on his last nerve with your refusal to do even the simplest tasks when he asks you to. Like I said before, a lot has been left unsaid in your version of the story. I am a rational, intelligent, mature person too, but there have been times when I have wanted to chuck something across a room when driven temporarily insane by the behavior of teenagers, and I know some men might have a harder time keeping the testosterone in check in these situations. Be glad it was a clock that got broken.
What should you do? Any simple task an adult asks you to, even if you think it's "so totally unfair" and the adult in question is "such a (expletive deleted)". Then go pout in your room and write poetry about how awful adults are for making you get up and walk into another room and push a button on a clock.
(Gee, can anybody tell I'm getting weary of parenting a teen?)
Wait, I'll save you the time of having to reply to this post, so you can get back to flea-picking:
