Is it normal to like your best friends sister?

Make sure you friend is ok with it first, I dated my brother's best friend and he didn't talk to me for a month. He was still friends as usual with his best friend but with me and my brother it really put a strain on our relationship. Eventually he got over it and we all hung out and it was great... but when me and him broke up my brother didn't talk to me for another month and said he knew I would end up messing it up and that's why he didn't want me dating his friend. Kepp in mind that if you two don't work out in the long run it might be awkward for all of you.

im dating my brothers best friend, it's slightly awkward, but it's just life+love isnt it? Obviously, check with your friend first, make sure he's okay with it... but apart from all that, yep, its normal, go for it=D!

Go for it, if it's ok with everyone. If your friend isn't ok, tell him if you get married, you'll be bros! What's better than that?

Definitely check with your friend first. If he's cool with it, do what you will.

Just check with your mate first, as sisters may be off limits, and also it can make things a little weird

My friend is dating his friends sister... It can be awkward, especially if he starts hanging around you guys when you just want to be alone. But hey, go for it.
