virtualizing

when Miriam was hit with tzara'as, Aron told Moshe "let her not be as a dead person

and (because I am her brother) it is as if half of me is eaten"

This is how we must look at our fellow Jews,  to feel their pain as though it is ours, and to do whatever we can to alleviate it. The opposite is also true, rejoicing with our own when great things happen.

As we see with in regard to Yakov blessing Efrayim and Menashe, one of the blessings was that others bless by their name because when his right hand was on Menashe because he was on a higher level then Efrayim, Efrayim was not jealous of Menashe, and Menashe did not get haughty because of this. (Rashi, vayechi)

Also we see in parshas ve'era: when Moshe was appointed 

to rescue the Jews from Egypt, it says about Aron "And he was happy in his heart" He was happy that his brother was chosen for the mission.

Basically, we "virtualize" the situation. Good times always!
