Ralf74: I paid for a man's groceries one day but i can't remember if it was because he forgot his wallet or didnt have enough money? It was a while ago. I was starting to wish I didn't after he kept thanking me and waited for me to get out so he could thank me again and again, it was becoming humiliating.
I do a random act of kindness every day... but the only rule is I dont tell anyone about it or it does not count.. and I feel quite disappointed if I miss out .. its been such a long running habit .. almost 15 years now..
And NO I am not going to tell you what sort of things I do.. you can figure it out for yourself.. as long as its a selfless (as opposed to Selfish) act its counts. If you get any benefit from it .. that does not count either!
