I love what you said "kindness is free". I know that is why many people stop sharing on forums like this or work forums etc. I understand people being leery about stuff but it is aggravating when people are nice and everyone starts to question their motives and speculate.
Not only your grandfather said that ! my grandfather also used to say " If your purpose is helping others, you won't look after their comments unless they are encourage your help ". You could know that, Yeah. People often forget that kindness is free.
While you're concerned about how you feel them, God is more concerned about your purpose and quite frankly they weren't included in it. Perform a random act of kindness.
