How does your life compare to Homer Simpson's?
We're all around the same age that Homer is in the series. They've referenced a few different ages throughout its history but he's always been roughly 34-40 years old.
He's got a stable, decent paying career but has also tried his hand at a number of other business ventures and jobs. He's got a decent size house with a nice yard in the suburbs. He has a core group of friends and coworkers that he sees on an almost daily basis. He has time to pursue his hobbies. He's got 3 kids and a loving wife that puts up with his shenanigans for the most part. He has a love/hate relationship with his elderly father and has an (mostly) absent mother. An underachieving son who he loves but constantly tests his patience. Has a bit of a drinking problem. Has had numerous run-ins with the mob and law enforcement.
The list goes on...
Edit: a lot of people have commented relating to other characters better so I'd love to hear those too if that applies.
