I don t understand him a little, so please comment on 10

Hehe, women are the most selfish animals, everything is for their own sake, and they will always blame others when they encounter problems, but they will never blame themselves Not to mention some messy things in the front, it is actually very simple: he starts to like you, you feel that someone likes you, so you feel happy, and then he finds someone else, and you feel unhappy and lost.

Since you want to be a brother and sister with him, and he finds a girlfriend, you should feel happy? Where do these messy feelings come from? also said that other people's boys are this and that, you don't want to drink people to fall in love, you want people to have you all the time in their hearts, aren't you too selfish, and say that it is not a boy, to put it simply, people have found another girl, you feel uncomfortable in your heart, because there is someone who thinks about you, thinking about how good you should be, and now that people are not like this, you feel uncomfortable, and then you are looking for this and that reason, of course, I know that you didn't mean to.

All of these are unconscious reactions. All women are just like you.

Women will always lack a piece of clothing, and men will always lack a girlfriend, a classic saying!

Now that the friendship is weak, you can't change anything, because he has a girlfriend, it's hard to change, and now I can only silently hope in my heart that he and that girl are really happy...

In fact, boys are like this. There's one in my heart, but there's another around me It's not that he really likes you, it's just because boys are actually very easy to give up and he will paralyze himself, okay, I'll find another woman

Maybe one day he'll tell you that I still like you!

How to talk about this kind of thing, if you really don't like him, you won't care who he's with! Boys and girls have different views on feelings, girls like that ambiguous feeling, boys are not

Ask yourself, do you really have him in your heart or do you just like that momentary ambiguity?

Friendship doesn't change because of anything.

The reason you don't have him is because you take him too seriously!!

There can be no friendship between men and women if they don't have common interests and goals, and your friendship mixed with feelings should end early, after all, he is not the type you like.

b, d displacement and distance concept.

Displacement represents the change in the position of an object (particle) and is a directed line segment from the initial position to the last position, the magnitude of which is independent of the path, and the direction is from the beginning to the end.

The distance is the length of the trajectory of the particle.

A particle moves from one position in space to another, and the length of the trajectory is called the distance traveled by the particle in this process. Displacement and distance are two physical quantities with different properties, displacement is a vector quantity, with magnitude and direction, while distance is a scalar quantity, that is, a physical quantity with no direction and only magnitude. In rectilinear motion, the distance is the length of the rectilinear trajectory; In curvilinear motion, the distance is the length of the curve trajectory.

When an object returns to its original position after a period of time during motion, the distance is not zero, and the displacement is equal to zero.
