Friend: "I knew you would be the type of person to have knick-knacks all around your house."
Friend: "I mean, I knew that you would have little decorative type stuff in every room."
Friend: You have lots of little figurines, and knick-knacks."
I am not sure if it was a compliment, or an insult, or nothing? Hard to say. But I am sure if the phrase- "I knew you would be the sort of person that" ... isn't followed by
"and I like it", or
"it looks good",
it really shouldn't be said.
