Sitter shopping

So we decided that we should try to find a sitter for intermittent needs and for a date night every now and then.
My wife is more freaked out than me, but I have to say that whenever I hear of a kid disappearing,I worry that maybe it's not time for a sitter yet. Anyways, we had our first interview with this really nice woman, she is 39, loves kids, is very calming and the pets loved her. But, and there is a big but. She talked to us for 2 1/2 hours! about other peoples problems. These are not her problems, these are her clients problems,and I find that rude and offensive. My son was surprising comfortable with her, as soon as she came in, he warmed up to her in about 10 minutes which is pretty amazing, considering that he doesn't even do that, that quickly with people he has known his entire life. So, we listened, watched her interact with him, made mental judgments, etc. Then I went to put him to bed, thinking she would stay a few more minutes and then excuse herself. When I came back downstairs she was still here. Sat and listened again so another hour and a half. Ok, here's the thing. I get very little time with my wife. We rarely get early bedtimes. My son decided to go to bed an hour early, and I was very excited. I was actually going to get to talk to my wife about life and still have time to do some things around he house before going to bed. I know, it sounds like I am complaining. Well, I am. Don't you think that someone who has been a babysitter for 17 years would get that when we gethome, we want to be together and making a space for her and an interview was generous of us. An that she should make herself scarce after all of the important stuff was discussed? I mean, it's not like we invitedher over for a visit. This was an interview! Oh I am so pissed. I guess I shoudl be grateful, she talked herself right out of the job. We would have hired her if she hadn't kept blabbing on and on about her other clients kids, divorces, poor daycare situations,their finances, their custody agreements, their autistic children.... Oh I am so not even kidding! She actually told us more than that. Two things bug me. 1. I do not want her talking to anyone about our lives that way and 2. It is totally disrespectful to eat up my time like that. I just lost 2 1/2 hours I can never get back. Damn. What would you have said? anyone?I am wondering if we should let her down easy or just be blatantly honest. Look, we loved you, we think you would be great with our son, but you just talked too much and we want someone who has better boundaries and can pick up on the cues we are giving you, like yawning, getting up from our seats, excusing ourselves to go do other things.... and still you are talking! You need to listen more and talk less. or should we just say, sorry we are not going to hire anyone right now, we changed or minds. and lie.

I don't know, I am not sure, but one thing is for sure, the next interview will be at starbucks, for 1 hour and the baby will not be there.
Sooo disgusted!
