This was an amazing episode. Sarah Baker played one of the most likable characters I have ever seen on TV. The blunt and brutal honestly this episode showcased was awkward and uncomfortable but it still made you smile; probably because this level of honestly in real life is so rare.
I'm a guy so I have no idea if the lines in this episode are what a heavy girl would really say (or be thinking) but I'm sure it's not too far off if at all...just a hunch.
The one small example I can give the world is my experience with telling a girl the truth one time in my life. I was hanging out with a friend (the type of friend that both are feeling the waters with to see if there is more there). She mentions how her legs are getting a little chunky and that all her friends keep telling her that she looks fine. She asked me to give her my honest opinion, so I looked at her legs and examined the situation; I told her that her legs were in fact looking a little thicker, she immediately smiled and said, "See, that's why I like hanging out with you, you're honest!"
Excellent job on the episode (and the series) Louis, you never stop impressing me!
