People give and receive love for different reasons. And, different people FEEL loved for different reasons.
Someone wrote a book, "The Five Love Languagues" addressing that fact.
Some people FEEL loved when they are 1) touched, 2) spoken to with words of love, 3) given gifts of love, 4) shown acts of love or 5) spend quality time with the one they love.
Ennis made Jack FEEL loved and Jack made Ennis FEEL loved.
In the end, it's not what people DO that you remember, it's how they make you FEEL.
