Bad company corrupts good character

I live with this girl, she is a negative Nancy. We have lived together for 1.5 years now, but I haven't spent a lot of time with her because I didn't want to be corrupted. 

Today, I had an interview. Afterwards I had a really good long conversation with Jack. It was really positive. He listened to my interview. We debriefed it, and we talked a log about God's will and what needs to be done. It was really good. And though it was not all smiles and giggles. I walked away feeling encouraged. 

I went home. And I had a conversation with Nancy. Nancy just put in her 1 month notice. And in that, has been VERY VERY open about all she hates about our camp. Earlier today, I was thinking that it didn't actually bother me and she is just transitioning out poorly. 

But after our hour conversation, and hearing a lot of negative things about this place and my boss. I learned it does indeed bother me. I need to be careful with my words. She doesn't know about my journey that I am on with finding a new job and I know now I need to keep it that way or that influence will bring me down. 

What is crazy to me though, Nancy and jacks conversations were very similar in content to each other, but the heart, feeling and attitude behind it, dramatically different!!  

I see it to be really true... Bad company corrupts good character, I feel that even in these small doses.
