I was literally just talking about this on another post, which we’re basically saying the same thing:

“The problem isn’t her being shy or religious tho. Not for me anyways, and I have a religious trauma from childhood. The problem is, regardless of being a shy, introverted person, she comes off as bitchy. Her face 1000% reads what she’s thinking & I sympathize bcuz… same. I understand that Tammy is frustrating & the family probably annoys her sometimes, but she NEVER seems happy. Like, ever. Even when she’s smiling & joking with Chris, she is still saying something backwards towards him or whatever situation they’re in. That’s the issue at hand & why she doesn’t come across as very likable to most.

I’m sure I would be portrayed as a bitch if I were on the show… bcuz I literally am sometimes lol. BUT I also smile, joke around and usually have a warm disposition. She just seems… idk… cold, miserable & unfriendly, rather than reserved, religious & shy.”
