That is a very tricky question. I find that you'll just know when the time is right. You can even compare it to non-sincere experiences in the past. I can always tell in their eyes, or in the tone of their voice. :)......hope this helped!
All you can do is ask them.

A guy is sincere if he says the truth. And if he is honest.

The comparative form of "sincere" is "more sincere," while the superlative form is "most sincere." For example, you might say, "She is more sincere than her friend," and "He is the most sincere person I know." Unlike some adjectives, "sincere" does not form its comparative and superlative by simply adding "-er" or "-est."
Dont know how you wouldn't know you were using someone because your actions made the statement and they felt the way they did. You go to them with a sincere heart and let them know that you didnt mean to use them you just werent thinking right and it will never happen again.
yes
He is probably not mature enough to be sincere -- many people never get to the point where they can be sincere with other people, which is a sad fact of life. If you want a sincere friend, you will need to either wait for him to grow up emotionally, or find someone else.
thay ask them questions
One word for warm, sincere, and friendly is gracious.
* Right conscience can be found in someone who is upright in his /her doing, * some who really have the fear of God and know what is right and not just an infidel. * Someone in its right mind knowing what is good or bad and doing that which is good. * someone who is sincere and trustworthy.
