A quote reads:
‘Wanna know who loves you more… your wife or your dog?…lock them both in your trunk and see who’s happy to see you when you let them out.‘
Here’s the moral of the story (point):
And now, we understand the “unconditional” love of a dog. See why? Because the dog doesn’t ‘know’ (nor understand). So, even if you’re an “evil” person, the ‘dog’ will still ‘love you’ (unconditionally).
