I'm a guy... I have 2 beautiful sisters in law who don't do anything other than go to work, get groceries, watch TV and sleep. It has been the same thing, year after year.
They're both attractive (and live together with 2 cats). One is in her late 20's and the other is in her early 30's. One of them has been in a couple of relationship a long, long time ago. The other one has never kissed a guy.
Well honestly, Its not your fight. I understand that you might be concerned about her but if she are not willing to find someone to be with then maybe she are not ready, or she don't want one right now. But if it really worries you, talk to her about it. Tell her that you want her to be happy with someone and if she gets upset about your opinion, just let it go. Don't worry yourself over someone else that doesn't seem to be worried about herself. let her live her life and if that is what she wants to do, then let her do it.
Have you ever considered that they might be gay? Or dating someone (even a guy) and just don't feel like sharing? That aside, think of the Delaney sisters - they lived together until they were 100
I'm thinking they are Lesbians, but like everyone else you need to stay out of it, you would not like anyone interfearing in your business. If they look happy let them be happy that's all that matters. They know how to go out and they probably do go out who's to say you know?
Congratulations on correctly pluralizing "sister in law." Sadly, that's an ability that's not normal--or at least not common, here in the US... About your sisters in law--can't help of thinking of Patty and Selma Bouvier (i.e., two sisters tortured by the repressed love that dares not speak its name, nudge). But really: they're their lives, after all, aren't they? Some people don't try because they're just not interested. It's almost cruel to be TOO concerned with "fixing" them. They like their cats--let them enjoy their lives the way they want to.
you sound like a good brother in law :)
