I apologize for the lack of discussion and stuff but it's a part of our strategy, unfortunately.
With some modification for the list above, this is how I treat everyone in my life (nope, not improving relationship or anything):
1. A friend ( same sex )
Little communication, I don't care about them, and I rarely rarely do any favor, or helping them. This doesn't include childhood friend situation, which I often do some favor.
2. A friend ( opposite sex )
A bit more communication, talking about everything, sex included. This does not include girlfriend nor fiancee however.
3. Someone you have a crush on
I don't have crush on girls, not anymore, if I do, pretend like I don't, and avoid any contact with them.
4. Close family member
They have an absolute trust, therefore, I'd listen to them, help them, or anything. This only include parents and immediate siblings. This does not include any relatives.
5. Workplace colleague/associate
As a junior executive, I have earned a lot of respect, so it the relationship was kinda awkward, hard to get close to them, unforunately when I'm being their superior.
6. Someone from internet ( aka here )
Depends, most of them being a retarded, though those I know, aren't. Therefore, I'm being extremely picky and selective of who I'd make friends over the internet.
7. Girlfriend/Fiancee/Potiential partner.
Since I'm not a fan of having an overnight relationship, therefore, I treat every relationship as dead serious. With that said, I have an extremely complicated ranking system and communication. Though, being very special I know that I act like an eroge protagonist, and such strategy somehow net me a lot of attraction from the girls.
For those that I'm not interested in, I do not reject them, rather, I play with their feeling, pretend that I don't understand their feeling, though give them no chance to advance and little room for mis-understanding.
For those that I'm interested in, she will have to go through a qualification test, which is sweet and bitter. I will also pretend that I don't understand her feeling, though, give her chance to advance. If she takes it well, then she might make me to fall for her, which is very very tough for an eroge player like me I'd say.
