Can one say
a. I am thinking about that door of the house which is locked.
b. I am thinking about the door of the house which is locked.
c. I am thinking about that brother of John who is a doctor.
d. I am thinking about the brother of John who is a doctor.
?
Does (d) show that the speaker doesn't like that brother of John or not?
Is it disparaging towards the person in question?
Many thanks.
