As a PNM I did like that I got to see every house, it made me interested in a few that I thought I wouldn't like. I didn't really mind the conversations, although I can think of a few houses where I had awkward silences during the conversation.
As a sister I really disliked it. You never know who you're going to end up talking to...you might get someone that "knows" they don't want to be in your house
. I felt like the burden was on me to keep the conversation going, and sometimes it was like pulling teeth. I liked informal a lot better because those PNMs chose to be there.
