Question: I have two questions.

[KIMJONGEUN]

Example.
Dr. Laura: Is your sister a little bratty and petty in general? I mean, is she a little thorn in the side of you guys in the family in general, or is this a very unusual behavior?

Question.
I wonder what the following means.

1. bratty and petty
2. thorn in the side of you

[Barb_D]

bratty - spoiled, expects to get what she wants
petty - gets annoyed about little things easily
thorn in your side - something that is constantly irritating
