How do you know if someone sincere or not ?

I'm not really good at judging character. So I want to know what does it take to know if someone is sincere or not?
It will be helpful if you can tell me your opinion/story about this, like your real experience
Oh btw I want to know too if someone is tsundere/not

 

For tsundere... All I can say is don't expect tsundere to go...
"Here! I made you this! It's not because I care for you or anything! "
.
.
.
Then again... There might be actual people like that...
As for the sincere part... Can't help you there... I too, cannot tell...

 

It's easy to know if someone is Tsundere or not, it's real life? then no, because it's a fictional personality type in Japanese animation.

 

When they send you memes to destroy the crippling depression of yours...
That's sincerity.

 

Facial expressions, the eyes, body expressions, the voice. That's is to tell who is sincere and who isn't.

Tsundere?
Mmmm....Baka!

 

What about the opposite, and they sincerely wish to destroy you?~

 

Jokes aside... It's maybe vague but... WHEN YOU NEED SOMEBODY THE MOST.... They are there for you.

 

Body language, facial expression, speech tone, past actions.. it’s a combination of many things.

 

From the way (s)he help you and your identity

If you are a silkpant, a rich 2nd generation young master, trust me they will sincerely help you (for money)

 

You lick their sweat ,you can tell because it has the taste of a liar

 

Wise Man, I always believed that when they found out your "mighty treasure chest" in that "secretly dark folder" in thy computer and fap to that.. that will lead to NTR destruction.

 

Use instinct

 

Well you try really, that's about all you can do, noone can with 100% certainty define whether or not another person is sincere or incinsere in all cases, though in most cases as long as you've been exposed to a decent amount of social interactions you'll learn it naturally, not conciously, but it'll happend in your subconcious.

 

Face reality. There' no such thing as sincerity.

 

Emm, u need to learn how to read people thought to know whether they are sincere or not. No other way. As any people nowadays could be a hypocrite inside...

 

Get someone opinion 1 or 2 person about that "sincerity"and choose the wise ones.

 

Sincerity only goes so far though, they might want to be there but can't due to life happening or you might not let them know well enough or at all and they don't even know what you need from them. Just because someone feels like people aren't there for them (which is a sign of depression and similar issues sometimes) doesn't mean people around them don't care or are insincere.

 

Time is what is needed to judge someone. You can only judge someone once you spend some time around them. I know some people that are pretty nice but I wouldn't really want to really be around them all the time. One of them is pretty loud and always interrupt when another person talks while the other always trys to correct you for the most part they are good people. For tsundere do the even exist outside of manga/anime?

 

Pfft

 

I hope tsundere is real.
I dont know but you can feel it, look around them. I always sit on the corner of class.
