I might be feeding you out of some self interest.
I might be giving you food by mistake.
Perhaps i simply dont like that dish myself.
Regardless of which…..your stomach gets as full as if i harboured some altruistic goal.
Would you prefer someone who lectures you or steals your freedom out of “love” and “for your own good” or someone who gives you a blanket when you´re cold for any reason, a selfish one included?
