Q: Our 18-year-old son made only slightly better than average grades in high school and finished in the top half of his graduating class. He could have done better, but has a history of underachievement which we explain as boredom. He managed to get into a second-tier state college but has decided after one semester (and as one might expect, mediocre grades) that he doesn't want to go back. In fact, he's telling us that he doesn't want to go to college at all. Instead, he wants to become a diesel mechanic. Needless to say, we're very disappointed, but also conflicted. His father is in favor of this new plan, but I'm inclined to tell him that we'll pay for college only and that he is going to have to figure out how to pay for anything else. What are your thoughts on this?
