Considering a same person from different angle
As there is no bone in tongue, the twist of the same may be of any manner is possible. Similarly an action of a person is commented good manner as well as bad manner is also a common among humans. If we do a work to a person immediately on asked in order to avoid his waiting for our action, leads appreciation as finished at the required time but at the same time some person would have told that as he, the doing person, have no other work.Similarly when I went to a hospital with a relative for treatment, where I know doctor personally. The patient got admitted and the doctor took special care on my relative as he known to me well. After treatment, when I returned, another relative asked about the hospital and treatment. I with some appreciation in mind, told about the doctor's frequent visit on the patient. But the person enquired commented as whether doctor has no patient. This words hurt me well though the doctor is not anyway connected to me.
So, the comments whether bad or good, we should do our duty without minding is a lesson to me.
