This bugs me but...

Why does Lisa constantly say that she has no friends despite her friendship with Janey, it doesn't make sense!

Janey in many episodes is seen teasing her. I agree that her comments don't contrast with sleep overs etc. you see her and Janey and even Becky having, but again The Simpsons has many more inconsistencies like this. You see directors are given creative control, so unlike many other cartoons, they are allowed to dramatically change certain things to fit the episode. The best example is the constant changing of the Simpsons' residence. Jhonevan's signature. 07:42, January 16, 2012 (UTC)
