What do these guys do?

I'm surprised nobody has replied to this post. I was thinking the same thing. Woodrow seemed to have enough funds for drinks, dinners, spare parts, whatever, all without any evidence of earning a living.

I got the impression they're maybe car mechanics?

They sure seem to party & f-ck around a lot? Maybe a relative is paying for their booze and rent?

The whole movie is a metaphor for boys growing into men. Boys don't have jobs, but they always seem to have fun toys...

I'm not sure about Woodrow, but Aiden is apparently an artist. In one scene he says something like "I've been working on this drawing for a week. Haven't left the house." Artists don't make a ton of money, but once in a while they get a commission that can float them a few months.

Woodrow could've been anything. In the beginning before all the mess, he's kinda nerdy (who wears a sweater vest? lol) who could have any day job from accounting to retail sales.

I'm kinda glad that the movie doesn't distract us with unnecessary details about their lives. It creates a fantasy bubble that separates them from the real world. Sorta like--to a much greater degree--"Peewee's Big Adventure". What did that guy do for a living? Answer: who cares!

This movie was so scattered and all over the place...that it's difficult for me to assume anything. But I definitely know what you mean. They didn't have jobs. They didn't seem to have any source of income. But somehow they were still able to afford things. But then again, the more and more I watch this movie...I speculate that the entire movie was coming from Woodrow's point of view. Almost like an observation of internal insanity. I could be wrong. But that's what I think.
