People talk for themselves not for you, they are a body and you are a different body. The nature of man is to have everything therefore whatever you have that the next person does not , is taught off as been theirs. This in real sense teach us to guard ourselves at all time , and to remember what comes out of people's mouth are lies . Hence the more you avoid unwanted communication the more you save yourself from thieves. Would you want to look for strangers to talk too ?
