Today is going to be a hard day. It’s the first day after a three-week visit with my sister and my niece, and we are missing them hardcore. We look forward to their visits, which are usually a few times a year, but it’s bittersweet because we know there will be a goodbye at the end. My niece is 2 1/2 and she and my youngest are 9 months apart. They have always shared a special bond that seems to grow stronger each visit. Since they stayed for longer this time, it was especially hard to see the two of them separated.
