You ask for Help. They are able to but they won't offer it.
They ask for help. You can't but you go out of your way to offer it.
The difference is not that they had a reason to not help you and that you didn't have a reason to not help them.
The difference between Them and You is that its not their nature but that its your nature.. You were Born and engraved in Kindness, Its something that comes naturally out of you.. To not help, would be defying Oneself..
