If there was any real reason besides pure laziness for him to only show up to college for 4 weeks, they would have explained their situation in the original post.
Not only that but all colleges accommodate for situations of that magnitude, and this wasn't just a last-minute thing, he stopped going to school by early october.
The real beauty of America is that as long has you work hard and put in time, you can achieve financial success, which this person clearly isn't doing by showing up for only 4 weeks of college. Not just "anybody" can do that sadly.
