Their happiness, theirs

A quote once said "Smiles are infectious...", can happiness be infectious too?

I have been feeling happy for others too often recently, so much that I wonder if I'm still sane, that I wonder if I'm genuinely feeling for them... Where have those feelings of envy and jealousy gone too? Perhaps it is a good thing, perhaps I'm cultivating the positive feelings after reading that Dalai Lama & scientists' experiment?

A friend left for her dream to further her studies, I felt so glad for her. A friend landed in her dream job (well, I think it is since she has nothing else in mind), it was good news and I felt happy for her. Another friend left Singapore probably for good to work in another exciting country. I thought it was a good thing! My sister is having better prospects in her current company, I think she's getting luckier... A mate I used to like a whole lot, and still do (as a friend) is falling in love, I actually am excited for him. A guy I used to go out with is happily married with 2 kids, I think he's happy and I'm too for him.

Am I still normal? Slight abnormal?? Why am I soaking in their happiness?? It's a funny feeling... I laid on bed for a long time last night, wondering why. I should be looking at mine, soon... in fact, I need to eh!
