Yeah, I've got to agree with fshfanatic...there are very few (if any) situations where we can yell at anyone and say that they are being a horrible parent. Maybe if they left their child locked in a car out in the sun, or something. I can see losing it then...
Many people don't keep an eye on their children and let them get away with murder, while some people OVERdo it and aggressively discipline them for everything they do, including "talking too much" (pretty common one there, I've noticed) and just being children - touching stuff on the shelf, asking questions and being curious...
No matter how dedicated an aquarist you are, being a hero to fish by being a bully to people just doesn't make sense to me.
