I don't know, depends on the person. I think it's pretty cute (since they were right next to each other) lol

I think it was cute they were on the couch together. But as brite said it they were a distance away wouldnt excite me at all.

It seems to be great friendship in the relationship. Only couples who are also best friends tend to be more laid back and comfortable in expressing themselves in this way. They get each other. I do think for an understanding like this to occur though, they should have spent some time around each other. And, hopefully, your brother isn't just cutting corners to take the easier route to marriage lol His gf can not wear a ring pic.:p
