Do you categorize people?

Do you categorize people?
I divide people into three categories - tomatoes, apples, and grapes.
Tomatoes, which are red outside and inside, are people who have my full trust and esteem.
Apples are red outside but white inside, and this means I'm cordial and friendly to them on a superficial level, as they are not completely trustworthy.
Grapes, on the other hand, are hopeless.
What about you?
