Do you think all soft speaking people are good.In our life we will be coming across many people. Some people talks very soft and friendly and some talks very loud and straightforward. Generally the people who speak very soft are supposed to be very good person and who shouts are bad persons.
But 100% it may not be correct. I had a distant relative who talks very soft and friendly. But I heard that he has beaten his parents as they have shared some of their money to the needy people. When I heard this I couldn't believe it. So what we hear and what we see may not be the real personality of the person. We will know their real attitude when such situation arises. For the sake of some money if somebody is troubling his parents, we can't treat him as good person even though he is good with all people and very soft spoken.
If somebody has done a mistake some people shouts and they will forget about that once for all. But some people just don't say anything and slightly say be careful. But they keep it in their mind and when a chance comes they will penalise him heavily.
I always say who are very soft spoken and good with you may not be that good all the times with all.
