My dear Jack, it’s a very rare family that will allow you to date two sisters successively. You were interested in the older sister but you went for the younger once the older one travelled out of the country. Which should make you question what you really want? Was it her you wanted or just a woman? Any woman seemed to fit your bill, including her younger sister. If you didn’t have an awful relationship with that younger sister this discussion will be moot. You won’t be mailing me. It’s because that relationship broke up you renewed your interest in the elder sister.
