Reborn:
My two cents first as a parent of an almost 18 year old I'd kick his ass if he did that to someone. I always loved the witness mentality "screw your brother but if he is now longer in the "truth" F*** him over".
Do I think you should forgive a debt ya if the person was struggling and had kids but a little brat that asked a favor then hides. Funny my monster Father in law always looked at the debt thing that way he would just burn himself out in a community take take take until they would almost run him out on a rail!!!
I understand that your irked, venting is great and having a place to vent is great but you can't expect them all to be nice or agree that my dear is life
