Whenever we observe our loved ones being dull or weeping inside, we try to do some type of fun and make them smile. But sometimes it should be noted that, few people takes your intention in wrong way thinking that you are making fun of them while they are weeping and thus might lead to total misunderstandings.
So instead of making smile, it will be better, if you start feeling their pain and cry in front of them. This will make the opposite person feel pity and come to you and console, because you are suffering for their problem. Thus they get diverted from their problem and forgets to cry.
