Mother Digging Us Out?

If you live on the east coast, then you know that today we got a crap-load of snow.

My brother is 24 and still lives at home. As if that isn't bad enough, his fiancee that doesn't even like him lives with us.

He went to a year and a half of tech school and she went to... well... she took a few online courses in sociology and said she went to college. She never finished.

Anyway, he's lazy. He's a 8 year old boy that likes video games, magic the gathering, and thinks he knows a lot of random trivia which he spouts out at random. This random trivia? Is made up by him that only he believes. He likes things that, quite honestly, straight men just don't like. (Hailee and Hillary Duff? Material Girl? I mean honestly. Gay.) He's just in the closet. Nothing wrong with being gay, but he just... won't come out.

Anywho, he's a do nothing. He doesn't contribute anything to society. For that matter, he doesn't even contribute to our family. He doesn't do "dirty" so he refuses to clean because he might... GET dirty. Which makes no sense. Or he's too lazy to move. He's overweight and constantly reaks as his fiancee needs to FORCE him to shower.

So I'm sitting in the living room and he pulls up to the house with my mom. They're home from work. They have groceries. He comes into the house, sits down and starts playing "Tomb Raider: Anniversary" for the Wii. It's a great game, but that doesn't give him license to play it rather than help with chores.
He didn't bring any groceries in, but he says "Can you get some shoes on and help with groceries?"
I stared blankly at him. "Are you helping with groceries?"
"I'm gonna play my game. I helped her SHOP."
And may I ask how hard THAT is to do? Walk around while my mother takes food off of a shelf so that he can shovel it into his face when he SHOULD be off buying his OWN food and stop leeching off his parents? He's 24!
So I do it because I don't want to make my mom do it alone. She's almost 60 years old. (Yes I have old(ish) parents.)
So I get all the groceries in (on my own, thank you.) and my mother is outside shoveling the driveway (because she won't pay for a plow truck). I'm already cold and tired from going back and forth for groceries and playing with the dogs earlier. She's shoveling the driveway and Scott is sitting there, playing his Wii game. Besides, I'm not very strong and do a lot of running around and dancing as it is (I'm in our school musical. I rehearse a lot), or I'd do it myself.
Scott is able-bodied, despite his weight, and he could DEFINITELY help by shoveling the driveway. But being a selfish, pigheaded, moron, he let my 60 year old mother shovel in the freezing cold.

There's definitely a point in time where the young need to leave the nest and grow up on their own.
