Ask her - she can only say yes or no.
my question is how can i convince my brother in law to get my sister to mental health
It's not adviseable - incetuous activity can cause serious psychological damage to you and your sister.
It is just down by proffeser Rowans lab by the beach.
prove/convince him that you're not a horndog bent on stripping his poor sister of her innocence.
What more can I say to convince you? Convince me with your actions.
Tell her that she could be infected
You can't. It's not really your business.
Lucas sister is into sandgem town on the hoer right by the beach
It's best to convince her! Or even try to bribe her.
Well, if you know that she has a boyfriend that's great. But never let your parents know. Let your sister tell them. Talk with your sister and convince her to tell your parents.
you need to tell her that something intresting will happen when she/he goes to sleep.
Need the circumstances surrounding the question, but see link.
