I don't believe a word of it........
Even rich people have reason.......I don't think she would buy all of the fish in one tank. Besides, rich people don't shop at wal-mart, lol. Guess who would do that though.........an average person who recently came into some money and wanted to 'splurge' or 'feel rich'. I've seen it in people, it's funny.
Even if the story is true.........you went back to argue with the woman? What's your problem? She let you take all that stuff that she spent her money on, because she could probably tell you would take better care of it. You harassed her on her property, over her son's irresponsibility/immaturity. That doesn't reflect too well on you.
We here are a minority. Most people have no clue how to properly take care of an aquarium.....it's understandable. It's a fairly complex hobby to be involved in that looks very attractive to the average person; who is usually met with failure because they don't realize that the net has websites where people just talk about taking care of fish.
Honestly, those fish don't look like they've been in a tank where the dead fish out number the living, with no filtration for 3 days.......if you made up the story for fear that the people on these boards would chew you out for overstocking your 20g (similar to how you "bitych" that woman) then I'm sorry you felt that way.
