. I know I shouldn't have listened but
um.... why not?
she was in your house, in your basement, in a public area where you had been with her moments earlier... it's not like she was a guest in a private bedroom with the door closed and you listening at the keyhole... the legal term would be "no expectation of privacy". she was in a communal space in your home, where you could reasonably be expected to return...
indeed if she had used half a brain, she would have *expected* to be overheard.
which makes me wonder if she's self-absorbed and without empathy, or if she lacks impulse control, or if she has some underground agenda that is served by having you hear those comments.
She said they were cute and seemed interested in them and ...
this is what I heard- "Those things are so f****** gross! Why would someone ever keep wild animals in their house? They smell like s*** too. All the clothes hanging up there are going to smell terrible when those things finally go outside. Hopefully she doesn't keep all of those- she already has three grown ones outside. I don't understand why someone would want to have such disgusting animals, especially in their home!"
see now that's where it would bother me. I prefer things to be <underneath> the same as they are <on the surface>. if someone were to say "gee they're cute but they kinda stink" I'm all good with it. if they were to say "doesn't the smell get in your clothes?" I'm all good with that too.
but "oh how sweet, how cute... how gross and disgusting, they smell like s*** " ... now that makes me squinty eyed and distrustful because if I *BOUGHT* the how sweet how cute act, I now know I can't trust what she says to reflect what she really thinks. and the degree to which I was fooled by that is the degree to which I could be fooled on more important subjects.
In addition, to imply, quite directly, that there was something *wrong* with me for wanting to keep them... the "why would someone keep those disgusting things" gets mighty close to that territory. to imply that I have no social skills (she's going to wear those stinky clothes), and that I have no judgement (clearly anyone with good judgement wouln't want more than 3)... well that's a whole lot of opinions that are getting mighty personal, and aren't about the chicks at all, but about me.
attitudinally speaking, "I think they're cute but they stink so I wouldn't want to keep them in my house" is a whole lot different than "I find it totally disgusting that you keep them in the house and are going to go around with your close smelling of chicken s*** and I can't understand what's wrong with you that you would do that." it's my opinion that the second statement is pretty close to what was meant.
seriously, someone who has all those kinds of opinions about me... well, they don't need to be in my house. probably not in my social circle in any way at all. people who say one thing to my face, and another about me to my back are not to be trusted. so if it were me, I'd be all done with her. I'd be civil to her in family social settings and that would be the extent of our social interaction. it would be the last time she was in my house... life's too complex already to invite interaction with people who make it harder.
as to what to do at the time... well I'd have to assume, since the setting didn't call for a expectation of privacy, that she expected me to hear her, or at least didn't care if I did or not.
on a good day, I might have taken the high road and turned a cheek, and used the opportunity to educate her on all things chicken.
on a bad day, I might have said "I'm sorry you find them so gross and my judgement so poor. I won't impose on your sensibilities any further. I'll get your coat and see you to the door."
One of the ways people get away with repeated bouts of bad behavior that creates havoc with others is that folks don't call them on it, they just take it and stew about it later. Life's too short. If I've got a useful redirect to apply, I'll use it, otherwise I'll just call it what it is, right there on the spot. they won't find that comfortable, but that's really ok. no need to get in a wresting match with them about it, just call it by it's name and then end the encounter. and then I'll remember who I'm dealing with in the future.
