My sister is one years younger than I and throughout our teens and early 20s she was a silly person.
1) she used to look at me angry all the time.
2) I could not talk properly and she said 'at least I could talk properly'.
3) She had to have the police drop her off home for acting like a prat in the city centre.
4) she always looked at me angrily and talked to me angrily when coming back home.
5) She used to just say one word when replying to my questions like someone who is not interested in me.
6) Many more
She think she's never done anything wrong but she has.
Would you class hey as mentally ill?
When can you expect yours?
