met people who can change others emotions...I have some ideas, but not sure how well it could turn out. I say, ressarch! -^^- lol.
My idea: Try imagining the person with the emotion you want them to feel. Positive energy entering thei body, or negitive.
If anything, find a way that makes you feel comfortable and keep trying it out, if t does work the first time, don't give up. -nod nod-
