<human>: I'll start.

A while back a friend of mine (we'll call her "Stacey") ...well her friend John started dating someone I knew.  Stacey asked me my opinion on this girl John was dating, and I told her what I knew; She was crazy, a drunk, and obnoxious, a total fake... in slightly more words and in a slightly more eloquent fashion. Finishing my statement with, "I don't know this girl anymore and haven't talked to her in years, so maybe she's changed, so just keep this info. to yourself.  But that's what I remember about her."

Well, Stacey had a big mouth, and what I told her got around to new John's new girl.  New girl sends me a message about how hurt she was, she thought we were friends, how could I, and ending with, "I thought you were a better person.  I thought you were one of the nice guys."

Some time later I tracked new girl down and apologized for being such a jerk, and turns out she's a better person than me.  She accepted my apology and has never brought it up since.

Summarize the given text in a few sentences.
<bot>: Talked crap.  Got caught.  Felt badman.  Don't talk behind peoples' backs anymore.
