So, what makes you happy in the game?

A really good team makes me happy.
A good drop after a long dry spell makes me happy.
People that are nice just to be nice make me happy. (An extremely nice tank gave my bird a very special bow today just because I might "find it useful some day". It really made my day.)
Helping newbies makes me happy.
Giving away stuff makes me happy.

What about you? What made you smile today?
