Many times in Life it happens, at several points in Life all readers must have experienced it, that the person u had selflessly helped was not there at the time u needed help! The term "not there" includes the help denied...!
I sometimes, infact often, think that even if help someone going out of ur way, in every possible manner they don't reciprocate. They memory of ppl now-a-days has higher half-life it seems!
Readers, at that point of time, don't we regret y v had helped that person in past? Well...what can b done? Life is like that...
