I would hazzard a guess that Tori has probably had problems with this partular parent. Most parents are wonderful and have every right to do other things without their children, when they are in paid care. However, sometimes, we do get parents who don't pay on time, are habitually late, don't sent the right equipment, clothes, nappies, SHOES! (I kid you not!) and I would imagine that this was the straw that broke the camels back.
I really wish it hadn't degenerated into a massive row, over there, Tori needed to sound off. Her only fault was probably not posting somewhere, where others have been there.
CM's need to sound off about their work, like everyone else and we all know that DH's couldn't care less, their day is always worse!
