I don't know how I can ask my question properly but suppose there are two girls and for me they look like each other so much..So I would like to ask one of them is that if they are relative ..so What is the natural way to ask that?
Imaginary conversation:
Me: Hi I always think that you and Beth look so alike.So do you have any kinship relation with her or any connection on blood with her ? ( I just made up the second sentence )
She : yeah we have...
