Only human...

We do things as people that everyone does and that is making mistakes and that is fine it's when everyone find out and starts to rips into you for what has happened  in the past at the time  you probably didn't know what you was doing may get you into shit and that is ok because everyone makes them but why couldn't it just be expected by other people...
one reason and that is that it not there mistake that can't learn that much from it unless they have lived it.
Anyone can give advice but that doesn't mean the person is going to follow it but people learn from there OWN mistake not other peoples so stop ripping into that person and be there and help them learn of it.
