I really do hate it when people let their children run loose, not just at the pet stores, but everywhere. I have 2 little girls, 6 years and 2 years old. The older one knows that she is to stay by the adults, and the little one is learning, but still has to be snatched up and held most of the time.
I was at a fish shop yesterday, and there was a little boy, probably not more than 4 putting his hand in a tank of Niger Triggers, which will bite. Not a parent to be seen, so I took it upon myself to pull him away and walk him to the front counter and the guy working there took him by the hand and found his parents, who said "Oh Jimmy there you are, we were wondering where you went". I wanted to drag the parents outside and give them my lecture about kids, and how to properly raise them.
It seems all to often these days that the parents just dont care as much, or have no sort of dicipline for their children. I know that if I would have run off like that, I would have got a smack on the rear right there, and my kids would too. Funny thing is, I'm only 26, and some of these parents are much older than me, and more than likely were raised like I was.
