huh, I can’t go home every weekend but I do like to eat alone. For various reasons: 1) the tradition of my nation: eating while talking is uncouth and disrespectful 2) eating alone saves a lot of time-when I eat alone I eat as fast as possible thus saving precious time for other things.
If I want to make friends and enjoy society, I would go to clubs and debating unions and all that; eating alone and going home ever weekends are indications of nothing, they are just personal habits, like some people enjoy pulling all nighter for no manifest reasons. </p>

It could be that they are afraid of eating too much or something like that. Some juniors, for example, once told me that ‘when you go to college, avoid school cafeteria and the dinning hall. Food there is so good and you’ll get yourself stuffed and you’ll be as fat as a suckling pig.’ :D</p>
