Empty Hard Disk

Just now my aunt was talking to DenDen, telling him how good or bad some people (relatives) are. I told her not to do that anymore because DenDen is just a baby, his new hard disk is empty, ready to store data. I feel strongly that he should be given a chance to decide for himself what's good, what's bad, instead of letting other people's experiences affect him.

For adults, we are easily affected by what people say or gossiped. We judge base on what we hear. Come to think of it, is it fair?
