Unforgotten

Dear sister, we posed for a family portrait today.  You were missing from it.
Dear sister, everything comes in even numbered packages.  We always have an extra because without you we are odd.
Dear sister, a dear friend stood as my maid of honor today.  That place was yours.
Dear sister, you are an aunt!  If you were here, you would be rocking this baby.
Dear sister, I called my best friend after a tough day at work.  I would have called you, too.
Dear sister, our grandmother left here to meet you today.  I'll miss her like crazy, but what fun you two will have!
Dear sister, would you believe three women at once styled my hair for our brother's wedding?  The salon chair beside me sat empty.
Dear sister, my daughters were fighting today over the bedroom they share.  You and I might have done that.
Dear sister, sometimes I feel frustrated and discouraged.  I fight because I have the chances you did not.
Dear sister, I found a child whose household is separated.  I fill in the blanks as best I can, because I know the empty places when family is sundered.
Dear sister, I ran into an impossible situation and was unsure whether to act.  I made a difficult judgment call because you could not, but I could.
Dear sister, another birthday is coming.  You did not live long enough to have a birthday, but I remember you.
