As much as we try to screen families and kids, we can still be surprised...pleasant ly or not! I once took on a family because I HAD to. I didn't want to...the visit was immediately after a family that I wanted SO bad....also the only family to ever turn me down! So, during the visit, I wasn't into it, then was in a situation where I felt I had to choice. 4 years later, they are awesome. I'm now with their second child. Our entire families have become friends, and we even mix business with pleasure on occasion. They've had us over for dinner and we've spent days off at the beach together!
