Why was the neighbor hating on the little girl's lemonade stand?
Here are my theories:
1) Neighbor planned to have a lemonade stand herself
2) Neighbor has bad memories of no one buying her lemonade as a child
3) Neighbor thinks lemonade stand brings a bad element to the neighborhood
4) Neighbor works for the I.R.S. and wants these monies reported
5) Neighbor is protecting the unaware buyer because the lemons aren't fresh and could cause serious problems after drinking
6) Neighbor is unstable and full or hater-ade
7) Neighbor didn't have 50 cent to buy a cup and she was really thristy
8) Neighbor thinks the little girl is really in some secret cult
9) Neighbor is part of a secret organization that monitors neighborhood lemonade stands
10) Neighbor needs a damn life...leave the kid alone!
