Heh.
That is a fortunate thing, indeed.
Last time that happened, I over-reacted and kicked open the door...
She wasn't letting me in, nobody was coming home for a long time, I had to get inside, and I know my sister pretty well, and as long as she was entertained by it, she would not let me in... and things like this she finds endlessly entertaining.
But, I think it's begun to become less so... because she's started unlocking the door while I'm pacing and/or waiting for someone to get home, and laughing at my stupidity when I find out it was unlocked for so long.
Either way, I am not kicking down that door again unless I have good reason.
Turns out that door is expensive.
True.
I think of yelling as some other form of communication or a way to enhance the meaning of the words to us (which tends to fail, whether it's realized or not, to help the communication to others) and screaming more of a form of easing the effect of a great amount, possibly too much, and too stressful an amount, of almost any kind of feeling.
But that's only my impression of them... I'm not really sure.
What's your say on that?
