I believe everything happens for a reason. We might not understand the reason at the time, but there is always a reason. We may never discover the real reason for an event, but if we look hard enough, we will find the little lessons that make us see things differently.
And sometimes, it's the cruel fate that was issued to a little kitten that force you to realize that, even if the choice fills you with guilt, your decision was the best for all involved.
You're going to have to give me a moment here while I set the stage for what will seem like an odd lesson.
