There isn't a parent alive who hasn't made a mistake at one time or another. After all, parents are human too..
Sis got an extra slice of pie when you were 11?
Mom always wished you could be more like "that nice boy down the street" when you knew he was a bigger jerk than you'd ever be?
Parents stiffed you on that bike at Christmas time?
Or maybe it's something more recent that you've had a hard time forgiving?
In any case, now is the time to forgive those crazy people who brought you into this world.. some of us can't because our parents have passed on, but for those of you who can, call your mom and dad and let them know you still love them.. even if you couldn't have a pony.
