A polite gesture of thanks is usually given when someone lets someone out in traffic and so not receiving that shows a lack of appreciation and hence it does not motivate the person to do more good.
Context: "It makes me very unhappy when I let someone out in traffic and they dont acknowledge me"
Hypothesis: It motivates me to do more good when I let someone out in traffic and they don't even bother to say thank you
Based on the context, is the hypothesis true, false, or unknown?
