Yay, my sentence inspired a book. lol
I don't. At. All. What other attitude is there? You'll never ever figure out exactly why *that* girl behaved in *that* fashion at *that* moment...so who cares? Maybe her dog was hit by the garbage man earlier that day. Maybe the OP reminds her of her ex BF that dumped her an hour prior...who knows. The only thing I am sure of, based on the information provided, is that it had little or nothing to do with the OP. Any other extrapolations are meaningless ego/expectation games and accomplish nothing productive.
