I know I'm going to hear all sorts of replies that I don't understand because I don't have a teenage daughter, which I don't. I'm also going to hear that I'm insensitive and I'm encouraging alienation of this "sweet" young teenaged girl. I believe letting this sort of behavior go unchecked is much worse than that possibility, so here's my reply.
I can't believe Dear Prudence's response! ! Teenager or not this is an incredibly selfish and uncaring girl, and all this talk of going with the flow and not alienating her is just validating this behavior. It sounds to me that this girl was given a free ride most of her life, and now that the parents need her help, she thinks it's "unfair"! Well is it fair that Mom got sick, and that Dad has to pick up the slack? How much fun do you think they're having?
This princess needs to be taught some very real lessons, or she'll keep repeating this unacceptable behavior throughout her life. The improtant thing is not that she refuse to help, the important thing is that she thinks it's alright to ignore everyone else's wants and needs. She seems to think only she matters, and her desires are important. This is the attitude of a five year old. This has to be changed
It seems to me it's time for some tough love. Here's what I would do. The daughter is working, so she shows at least the rudiments of maturity. As of now, if she's not already ( and my guess is not), have her start paying for room and board. Insist, not suggest, that she take on some of the chores and set undesireable (to her, at least) consequences if she does not comply . Then let her know who the parents are and STAND FIRM!
If she doesn't do her laundry, do not do it for her. She can wear smelly clothes. If she doesn't help with the meals, let her use HER money to eat out. If she doesn't contribute financially, refuse her access to the TV, phone and computer. Start off small and escalate the situation with each refusal. Whatever the circumstances, if she refuses to contribute to the good of her family, refuse to allow her to partake in the benefits.
She needs to learn two important lessons. One is that families need to stick together, because there is nothing more important in life, and two is that there are consequences to every decision she'll make in life, both good and bad.
A good hard dose of reality would do wonders here. She's old enough, she can deal with it!
