@canusernamebemyusername no,i mean ,something important in your life ,you never made it and someone you know ,met you after many years ..he thought you could have achieved this thing aready but you didnt ..so what would you say to him??as he reminded you of this things and nade you feel pain inside and just remember the whole thing like it was yestrday !! what would you say to him???

@exita Tell him what stopped you and why it happened. You can't help it and it's not like it was your choice to fail or anything but it happens sometimes. Try to get them to see that and be understanding.
