Is this person ever going to learn?

I know this one person who is like 25 and he barely goes to college. Some semester he decides to take it off and not do anything. When he was working he wouldn't help out paying bills around the house or anything while his roommate and brother pays everything. When he wants a new phone or something nice he won't buy it himself, but get his dad to get it for him. He seems so cheap and unreliable when you ask him for a favor. If it doesn't benefit him he won't do it and stay up all night and wake up at 3 in the afternoon. With myself I go to school full time, work too and when I get my check I decide to help around the house by paying the bills, which does mean I just can't buy anything, and when I joke around with him saying look at my old t-rex phone he mocks me in a bad way. Like he will say "what a loser you are with your phone. Why don't you get a iphone 5 or a S4. Your so poor." Its just stuff like that. I barely hang out with him, but when I do that's how he is. I wonder to myself is this kid ever going to grow up and act like an adult or rely on his daddy to buy him everything? Is this fair to the rest of us who work hard for money while the few act like spoiled selfish-less idiots?

No way is it fair. Ignore him at least you will have a proper life in the future.
