Erm so this might sound a bit weird, but is it weird that I talk to my sister boyfriend more than I speak to her? It's only cause we have a quite of things in common, and he can't really talk about them with my sister cause she's bit clueless on what we're speaking about lool
As long as you're not advancing on him in any way, no. I just recently got to meet my brother in law, we've been talking a lot and having tons of fun. Though in this situation my sister has also been there for most of that.
