How Can You Make Someone Happy When They Are Sad?

It’d help if you were specific in what they’re sad about but..
1.DON’t DO ANYTHING TO REMIND THE PERSON OF THE THING THEY’RE SAD ABOUT
2. Call them.. chat…. [if the person is a gurl... kinda weird if it was a guy...]
3. ask to hang out.. mall.. park… etc.

Depends on the relationship you already have with them. If you are lovers, and you really know that other person VERY well, you will also know that it’s often just a good sense of timing. I mean, let’s say the dog just ran through the garden when you had gone and planted new flowers. You and your lover stand there and observe the disaster. You could turn to them, pause and then say: So! Are ya horny?
If this person is a friend of the same gender, you might say nothing but put your arm around their back and hand on shoulder, squeeze, brief pause, and release. Then ask: is there anything within my power to make your day brighter? And they will say no, likely. So you can then say, well I’m right here for ya, should there be.
It all depends on the two people. Sometimes you have to say something like “I am so sorry you are going through this. It must really be frightening/upsetting/whatever. Put some concern in your voice and look right at them. Likely they will want to talk, but perhaps not. Don’t force it. Ask if they would appreciate a drink, like coffee or water or whatever is quickest. Don’t let them “cool off” without your attention and concern. Imagine if it was you.
You may react differently but I bet fear was one of the emotions nevertheless.
Hope I stimulated your thoughts.

Sometimes people don’t want to feel happy. They want to wallow in their sadness for a while. Then you can make him/her feel better by just sitting quietly. It may be hard for you, but it may be what he/she needs. Then after awhile, you could fart or something.
