It's great that you've been able to lead your sister into good opportunities! (riding your coattails). She's your sister & you love her. Family is a very precious thing in this world. It's a shame for both of you not to have spoken for years. Some of us are weaker than others in various things & various ways. It's a good thing there's many of us to spread the out the bad, & share the good. Family members aren't with us forever in this world. Sounds like one of your strengths is initiating things. It would be a wonderful thing for you to initiate good contact with your sister. Let her know you're happy for her & share & celebrate with her good fortune. It's something you both have in common (Dropkick Murphy), great conversation starter!
