So, when we act kindly or generously or seemingly selflessly, are we truly being selfless or do we do it because of how it makes us feel? Or, in worst case scenario because of what we can gain from being 'nice'?
Mostly, I am kind to people because like colditz says, they are human beings.
Occasionally, I do it for other reasons. eg we were at a family attraction. DS (3) was looking at things in tanks. He moved carefully sideways and accidentally bumped (very softly) into an older woman. The woman turned to my 3yo and screamed in his face "BLOODY KIDS" so I said in a very calm and nice voice, "DS, say sorry to the lady" and he say "sorry" very sweetly. She then turned her back on him. It made her look like an idiot and people round us started laughing at her behaviour. If I had shouted back at her, I would have looked like a fool, but because I was sweet and kind to her, she looked like the fool.
