The 3rd time I got disappointed to someone I've cared about.
I wasn't asked to spend xmas eve together, neither to celebrate new year's eve together, as a so-called 'good friend'.
I started to doubt about the term of 'good friend'.
Human relationship is the most tough one in life and also the most awful one.
You thought when you're nice to people, you'll be treated in same way and won't be left behind.
But no you won't. There're always personal interests and intentions involved.
And when you're smart enough to be able to see into it, you confused what's the right thing to do to human nature, and can't keep wondering why...

This is a cruel world. Perhaps being a good friend to your pets will do better to life than to any human beings.
