Some people have bad trait to get stuck in the past. All they do is ever regretting they did or didn't do this or that thing/deed. And God forbid if their past was better than the present! In this case a person will be lamenting bitterly, exasperating everybody around.
Beyond the shadow of any doubt we like to lead babblers about past offenses, afflictions, chagrins, etc. Bad or dirty words, said to you, may torment you till the old age. But ask yourself - why do you keep negative experiences and remember them over and over? I think this question will stay without any ground answer…
So, when it comes to rummaging in your past, stop yourself and change the stream into another channel! Remember all the good you have in your life at present and praise God for it!
