What a great picture of you two! I'm sorry for your loss. As someone who's lived far away from my parents and sibling for three decades I can really identify with how difficult it is to leave after a visit. Those handful of moments at the airport gate or driving away from our loved ones' driveway are damned difficult. After a while we know that the current of life sweeps us away and the pain subsides but it's right there waiting for your the next time which we get to experience if we're lucky.
