50 shades of happiness

There are many words for happiness,
And so many sorts as well.
There's euphoria, a grand word
That expresses the fireworks of happiness bursting inside,
And then there's glee,
Which seems just as strong, but squeakier.
Delight is an absolute happiness,
But not expressed as violently.
Exuberance and ecstasy are ultimate,
A punch of feeling,
While contentment is so much more peaceful.
But what I feel right now,
As I write deep, metaphorical poetry,
Is a sort of quiet satisfaction.
Not apparent in anything but my relaxed stance.
And really, satisfaction is the right thing to feel,
Considering I'm the only one in the bus with enough space to sit.
