I share TheDirtyDigger's sentiment... but if my kid really wanted to drop out before university graduation, s/he and I would have to sit down and have a long talk about it. If s/he can submit a convincing/persuading enough argument then I might consider the proposal. It all depends on why s/he feels the need to drop out and what alternative plans s/he has to do instead of further education.

Basically my question would be "so what do you want to do with your life instead?" - give me a long term plan. I wouldn't want my kid dropping out just for the sake of it without thinking about an alternative life plan and instead becoming a bum (especially if s/he's still living at home!!!)
