I can always tell when I feel like crying because my nose plugs up. Many times I feel that even though I may not actually cry. Some things just touch me, I guess.
Some years back, Microsoft ran a contest for grade school kids (I don't remember what the specific age group was). If you won, your school got free computers I think; something like that. The students had to complete this sentence:
The most powerful computer in the world would let me....
The winning entry was:
...see the world through someone else's eyes.
EVERY TIME, without fail, when I see that it just resonates because that's the kind of world I would like to live in. It means I would feel someone else's triumphs and sorrows as they would feel mine. We are not here for a minute and that's it. We forget that, in part, we are here to experience. Once we have that experience, we carry it with us where ever we go; it is a part of us, it changes us, it is how we evolve.
