Isn't being cringe-worthy (I'm old; this is how WE say it) subjective? Has the expression changed? I can only speak to my own cringing at something. She's also not dumb, as she can hear and speak just fine
As far as being an idiot... she does seem kinda slow, but not sure how that is a negative.
I personally didnt like her until she became the Cuck Princess and started pushing Thomas and the girls together. Also, her mom is arguably THE hottest in the entire game (Sorry, Amy!).
ps- your use of punctuation is interesting. Never seen commas between quotes before. What standard is that? I was taught that punctuation always goes inside the quote, even if it changes the meaning. I never liked that standard, personally. My grammar is decent, at best... But, your style just caught my attention and I find it interesting. Peace.
