Robert Heinlein was right when he observed that “being a mother is an attitude, not a biological relation.” Each year, on Mother’s day, I thank my lucky stars for my sister, my other mother. There is no one better, no one who loves and cares for me just like my mom. I knew this when I was little and she would take care of me and I am even more certain of it now. The best thing about having my sister is knowing that not only does she celebrate my happiest moments as much as I do, she’s there when I need support. I hit the sibling jackpot and I’ll admit this every day until my last day.
