An excellent senior should disappear or not appear in this world like gameover.

After all, the possibility of being friends after the relationship is over, not just two people, but four people (you, your current, your predecessor, ta's current).

Here we use mathematical probability to find out more intuitively how likely it is for two people to maintain a good friend relationship after ending their relationship.

The possibility of you and ta becoming friends =

The probability that you want each other to be friends Xta wants to be friends with you X the probability that you now (or in the future) accept ta as your friend Xta now (or in the future) accepts you as a friend of ta.

After simple mathematical calculation, you will find that as long as at least one of them is 0, there is no doubt that the possibility that you are eager to be friends with ta is also 0.

Of course, the human heart is very complicated, far from being as simple as the result calculated by mathematical formulas. You can say: both ta and I are keeping secrets from our predecessors, so the result will definitely be greater than 0.

If you think so, unfortunately, it underestimates people's emotional sensitivity.

Love is selfish. Who doesn't want to be the only one for each other?

After all, paper can't wrap fire. When a Pandora's box is accidentally discovered and opened, infinite possible results follow.

In fact, not all seniors can't be friends. For example, the following premise: you and ta may be good friends from the beginning, and you have a good relationship with several other people to establish a circle of friends. Until one day, you mistakenly classified the feelings of friendship as love and came together, but in the end, you found that you didn't get the happiness and feeling you deserved because you crossed the relationship of friends. So, you decide to be friends again, and you also find that being friends is happier than being in love.

Because you are very good friends, when you find that there is another half on both sides, your idea will be to sincerely bless each other.

However, it is impossible for most predecessors to leave 100% affection for each other. When you see that there is another person around that person, countless pasts, pasts, passions and noises between you and ta will constantly emerge in your mind.

Maybe ta doesn't care, but you hurt yourself. Is this friendship worth it?

Why does Ex-3 make countless people cry because they think of their predecessors?

Because:

People who obviously don't exist are back, but the past that has disappeared can't be retrieved.
