Yeah. Scared whatever it was right off with that manly woof! Now, that's a bark. Of course, giving you goosebumps probably wasn't the best of things, unless they were positive goosebumps. As in, Mike, you're the man. Or, the manly dog. Something like that. :)
There's a Marvel character this is reminding me of called Black Bolt. His super powers are sonic, so if he speaks, depending on how loud and how long, he devastate cities. Even a whisper can do major damage to things and people around him. Needless to say, he keeps quiet a lot.
Also, it's reminding of a man I know whose family said he didn't say much. But when he did, they listened, because it must be important.
One of those would seem to apply here. :)
The goosebumps came from the weirdness of Mike finally saying something for the first time and doing it in such an authoritative voice. As in the man who seldom spoke, it got my full, adrenaline attention and that's what had me out in the dark, armed to the teeth and in full defense mode.
I found nothing but was convinced it was an alien who beamed up as soon as it was detected. There's no point in letting a decent warning bark go to waste!
