That is why I will never agian work in retail- it's downright depressing. (I have a back up job for after colledge if all else fails- farrier) I work at a museum at a historic farm and lots of people feel the need to activley engage their kids to run and scream, to throw all of the dirt and straw I JUST swept up out of the bin so that the kids can have a chance to clean too. My sister is 4 and she just switched daycares. She used to be well manered and was learning to sound out simple words and spell words, but now she is a wild child, her teachers don't dicipline and teach her awful grammar. That's proof there that it's far more beneficial to take some effort and teach your own kid right from wrong! STILL if she EVER banged on the tank/cage of an animal I'd have her look me in the eye and tell me why it's wrong to bang on the cages so that she understood the harm she was doing. A 4 year old can grasp the concept that banging on the tank can scare my lizard.
