Kate Wolf sang a song called Some kind of love, and the line that jumps out at me went:
Some kind of love tears your heart,
When you knew it was wrong from the start,
But, try and explain the moth to the flame
Some kind of love tears your heart.

and another:
Some kind of love comes too soon
And that kind of love heals your wounds
When your wounds are all healed
And you're back on your wheels
They say "That kind of love came too soon."

The most troublesome word in our languabe is: EXPECTATIONS.
If someone has let you down, maybe you were too heavy for them.
