This is what writers do when they run out of ideas. They have high schoolers wanting to get married. Nevermind that in the '80s and '90s this didn't happen, even in really conservative circles. I know, I grew up in those times among very conservative people. I knew of noone who wanted to do that so young. Still several shows presented this as typical even through the '90s. The writers are too old and behind the times sometimes. It's just completely unrealistic, and logisitically impossible at that age. It's also inconsistent with Carol's character, turning her into someone really flighty and unthinking. The only realistic thing was the parents arguing about it. Most episodes of this show are enjoyable but this is definitely an exception.
