Well, I’m no Einstein, but I have my own theory of relativity.
Notice how when you’re happy, the world around you seems a little bit brighter? You don’t mind the heat too much, you don’t mind being stuck in the traffic a little longer just because some idiot in front of you dint clear the signal fast enough (you don’t even call the guy an idiot!!), how nothing can seem to get you down, how you notice even the less fortunate seem to be happy with what they have, how even when you a total anti-romantic, you go ‘Aww’ when you watch a couple sub-conspicuously reach for the each others hands to hold while walking (even though normally, you would yell out to them to get a room), and the sunset at the beach is never more perfect?
Now notice when you’re sad, you notice all the flaws in the world, you notice all the unhappiness around, and should you witness some happiness, you get all sarcastic and irritated and even more depressed? Then you’re always stuck at a signal that just won’t clear, all kids in different variations of cute-ness just seem irritating, couples seem nauseating and happy couples with cute kids make you want to rush to the terrace of the nearest building-and fling THEM down? Ever notice how even the sunset at the beach… nah ... sunsets at beaches are never less than perfect, that’s one thing that can’t be ruined, come rain or nauseating couples J
Now there isn’t a corollary (I believe that’s the term for it) to this:
When you’re happy and someone tells you something happy that happened to them, and you happen to like this person, then sure… the world just got a little brighter.
However, when you’re sad, hearing about something even sadder about anything or anyone does not make you feel better. It’s like when you’re really upset about something and you cant finish the food on your plate and want to throw it away, and you’re mom tells you to finish it, and to think about the people who don’t get a single decent meal in days, not only are you already upset, but you get more upset cause you have to finish the food, and to add to that you have the guilt of poor ill fed people to add to your sorrow.
Dunno about the food, but a big fat tub of choco-chip ice cream sure found its last day of existence!
