My father was very strict and uptight when it came to sex and I was never allowed to go on vacation with a boyfriend. I would just lie and say other people were going on the vacation with us, because everyone knows you can't have sex if other people will be there . For some reason this made it okay and my father could handle it. I'm 33 and have been on my own for almost 10 years and I STILL lie to my father when I go on vacation with boyfriends. Logically I know it's stupid and I can do whatever I want, but it's just easier to let him live in denial. Probably not the best way to handle such a situation, but it's the easiest.

I can't imagine that Dear Abby would tell this girl to lie, so I guess I agree with her advice assuming the girl wants to continue living with her parents.
If you got nothing to bring to the table - don't even bother sitting down.
