... i'd say, you're heart breaks when there's does, you rejoice when they do, you feel better when they're around; you wish the best for them, your worry about them, you become indignant when they are insulted or spoken negatively of, [you may argue with them, or get mad at them, but in the end you overlook it because of the value they have in your heart] and even if you don't think of them often, when they come to mind, you smile.
I feel this way about my friends and family, so idk, that could be love. LOL but i like them too! ♥
